Well, at least in this case, we could avoid calling `NtUserMessageCall` at the start of the procedure if the message is `WM_NCCREATE`, and then call it at the end of the `WM_NCCREATE` switch case instead of:
return unicode ? DefWindowProcW(hwnd, uMsg, wParam, lParam) : DefWindowProcA(hwnd, uMsg, wParam, lParam);which would avoid a double call to `NtUserMessageCall` I presume.
I've changed this in the most recent revision to only call `NtUserMessageCall` once instead of twice in the case of `WM_NCCREATE`.
Why isn't this using an atom like the normal class name? And why does it need new requests as opposed to extending `set_class_info`?

1. The idea behind using an enum instead of an atom was that there's a fixed set of builtin user32 window classes that can set "real" window class for an HWND, and looking up the atom each time was added complexity. We could store an atom instead though if you'd prefer that, although AFAIU that'd require a lookup each time since I don't think class atoms stay constant.
2. `set_class_info` is per window class, and my understanding was that that request was meant to set information for a specific window class. The real window class value is a per-HWND thing, meaning multiple HWNDs of the same window class could have different real class values. Pulling in the information to do this inside of `set_class_info` seems tricky, since we can't access the `struct window` without importing the definition into `server/class.c`.
Why isn't this using an atom like the normal class name?
We certainly can. Pros:
1. `NtUserGetClassName` can be slightly simplified in other-process-window case. 2. `NtUserGetClassName` will no longer need fallback-to-non-real-class behavior. We can simply set the real-class-atom to the normal-class-atom. 3. We'll no longer need `enum wine_real_class_id` as well as `real_class_id_str`.
However, there are a few questions that I couldn't find an optimal answer that you'll certainly like.
1. **Name-to-atom** mapping: a real-class-name (e.g. `Static`) has to be mapped *at some point* to an atom for use in `struct class`. When should the atoms be created?
1. Reserve (and possibly pin) the atoms on initialization[^init-by-whom]. If we go this route, we probably want to keep `wine_real_class_id` in some form, which means this is merely swapping one indirection for another.
2. Look up the atoms when `set_real_window_class_id` is called. This allows us to avoid reserving atoms at startup, but slows down initialization of certain user32 controls.
3. Other solutions: I don't believe there are any; please correct me if this is not the case.
2. **Atom-to-name** mapping: the set of possible "real class names" is fixed; the user cannot add more. On the other hand, the real-class-atom is an *indirection* that allows arbitrary "real class names." This is arguably a bloat[^that-can-be-justified]. Where should we introduce it?
1. Add a field (e.g. `WCHAR[9] real_class_name;`[^why-nine], +18 bytes[^mem] of memory use) to `WND` structure in `ntuser_private.h` for the cached real-class-name.
2. Add a server call (process context switch) in `NtUserGetClassName()` to fetch the real-class-name from the atom. This can slow down oleacc and/or UIAutomation APIs, although @cmcadams has a better insight.
3. Other solutions: I don't believe there are any; please correct me if this is not the case.
I'm okay with any of the choices above. I was merely raising this issue because the approaches above may end up adding more complexity.
[^init-by-whom]: This can happen in the server, `win32u.dll`, or `win32u.so`. [^that-can-be-justified]: I said "bloat" because we're allocating unnecessary resources, but this is not necessarily a bad thing if it makes code readable. [^why-nine]: The longest known real-class-names in the test are `ScrollBar` (9 characters) and `MDIClient` (9 characters). [^mem]: +6.25% for 64-bit. +9% for 32-bit.
And why does it need new requests as opposed to extending `set_class_info`?
Two windows can have the same class but *different* "real class names[^intended]."
To allow this, we have to change the role of `set_class_info` from
- "Fetch or modify the class used by the given window"
to
- "Fetch or modify the class used by the given window *as well as* window-specific information (real-class-name) not specified in the class."
[^intended]: Subclassing USER32 controls happens in per-window fashion, not per-class. The application can reuse the same custom class to subclass BUTTON and STATIC, for example.
