The merge request was extended, and another commit added to fix a major bug [related to GUIDs](https://gitlab.winehq.org/wine/wine/-/merge_requests/6130#note_76721) and other minor fixes. With stubs for both interfaces the games mentioned [on this thread](https://gitlab.winehq.org/wine/wine/-/merge_requests/6130#note_76698) now work without further patches.
