[PATCH 0/4] MR5137: win32u: Use strings for adapter names and use them in the adapter config keys.
I'm not completely sure what the expectations are regarding these registry key paths, but @afrantzis said Wayland reports adapters in an arbitrary order and this would let us find the right adapter config and their current settings based on their unique name instead.
Other drivers simply format the numeric ID themselves, though might not be 0-based index anymore.

This is wrong. The name should be a 4-digit string as it's on Windows.
I don't think this MR is going in the right direction.
(struct gdi_adapter).id is internal to each driver. So it doesn't have any use in win32u. It got exposed to win32u because of the win32u/user32 refactoring.
What you need to worry about is the map from GDI adapter name \.\DISPLAY* to wl_output. The map must be stable so that each \.\DISPLAY* should refer to the same wl_output or wl_output collection (concerning mirroring) when no output changes are detected. Better, keep this map consistent even after output changes so that each \.\DISPLAY* still points to the same wl_output.
The number index in \.\DISPLAY* is from (struct adapter).id, generated sequentially in update_display_cache_from_registry(). So what you need to do is to make sure that winewayland.drv knows how to map \.\DISPLAY* to each wl_output. What winex11.drv RandR 1.4 backend does is that it always adds the GDI adapter in the same order, so xrandr14_get_id() knows which RandR output a DISPLAY index points to.
So I guess you can always add GDI adapters with them sorted alphabetically by the wl_output name and keep this GDI display index to the wl_output map in winewayland.drv. For example, entry [0] "\.\DISPLAY1" -> "DP-1" and entry [1] "\.\DISPLAY2" -> "HDMI-1". And then you call (struct gdi_device_manager).add_adapter to add "DP-1" wl_output first so when "\.\DISPLAY1" is passed to winewayland.drv, you can know "\.\DISPLAY1" points to the first entry, which is "DP-1". I don't think \.\DISPLAY* indices are guaranteed to be the same across display changes so you can ignore output changes affecting GDI display indices for now because you can remap them due to a new display device initialization, which is what Wine does now. Then, of course, you'll need to update display devices when the reported wl_output array changes by responding to their events. You'll also need to make sure the map is the same when it's called from another process.
Finally, back to the original question of (struct gdi_adapter).id, you can pass the wl_output name internally in winewayland.drv the way you like. But such internal details shouldn't concern other graphics drivers and win32u.
This doesn't sound right though, and although I understand that this registry key may need to use the integer indices matching the .\DISPLAY indices, I think we'll then need to introduce some mapping in win32u to match these indices with the physical adapters reported by the drivers.
.\DISPLAY indices only correspond to the index the physical adapter was enumerated at, they do not match a specific physical adapter. Lets consider a scenario where a new adapter appears, such as when hot-plugging. Whether we sort the physical adapters or not on the driver side, and unless it ends up last, the mapping between .\DISPLAY indices and physical adapters will be different.
In win32u we use that registry key to save the display settings. The current and enumerated modes are refreshed on every enumeration, but the registry settings is kept from the last time it was written. When the .\DISPLAY to physical index mapping changes, we will incorrectly use the registry settings that was written for the old physical adapter, instead of creating one from scratch for that new adapter.
So in my opinion we need to have a physical adapter id -> logical index mapping in win32u, and keep the display settings linked to the physical adapters. This will also save a lot of complexity on the driver side as they won't need to sort anything anymore.

I agree that we should have a physical adapter id (or output name as in wl_output) to \.\DISPLAY* map. The map currently exists in graphics drivers. If we want to deduplicate code and put it in win32u, I think that's ok.
Ideally, we should let graphics drivers expose their physical adapters and outputs to win32u. Then we can build GDI adapters(logical adapters, that correspond to win32u outputs) and GDI monitors from the win32u physical display devices.
Then graphics driver API can use physical device information only to get and set device state, eliminating the need for something like X11DRV_ChangeDisplaySettings(), which uses GDI adapter names instead of physical device names, thus removing the need for GDI->physical device map. The D3DKMT* functions are worth looking into for defining such a graphics driver interface to win32u.
Anyway, this MR needs more thought.
Take winex11.drv for example, there are four functions that use GDI display names. They are X11DRV_ChangeDisplaySettings, X11DRV_GetCurrentDisplaySettings, X11DRV_GetDisplayDepth, and X11DRV_UpdateDisplayDevices. I think we would want to work towards the goal of using physical display names here so we can move the GDI display names to physical display names mapping to win32u. Since winex11.drv already have such a mapping but winewayland.drv doesn't. We could also support such a mapping in win32u first for winewayland.drv. And then gradually phase out the winex11.drv internal mapping. So the wl_output name should be in "struct monitor" instead.
I would prefer "struct gpu" or "struct adapter" for physical GPU and "struct monitor" for physical display outputs. Then "struct gdi_adapter" and "struct gdi_monitor" can be constructed from the physical display information. This way, we have a clear separation between physical and logical/GDI displays.
