I'm aware that this is a lose-lose scenario, due to EA not fixing their issue on the end, since it's either:
- Workaround the issue, but cause breaking changes outside of it - Do nothing, but EA app remains not working without manual intervention
And IMO, the second choice is better.
And many things can still be done, like having better documentation about the issue. For instance, Wine's wiki has a [Known Issues page](https://gitlab.winehq.org/wine/wine/-/wikis/Known-Issues), where this definitely belongs. Or maybe it could be added to the Arch Wiki as well.
Or [make changes to systems that set huge environment variables to be less wasteful](https://github.com/NixOS/nixpkgs/pull/451031) (which is nice even outside of this).
(And if there is still intention of doing a workaround for the issue... would it be possible to unset environment variables only if the executable `EADesktop.exe` is launched, to minimize the impact of breaking changes elsewhere?)
