Really I'm surprised nobody's done "WinBox" yet. Proton kinda covers that except it runs in Linux, not Windows. I dunno how it handles old Windows games as I've got zero nostalgia for those, my Steam Deck mostly runs modern stuff from small teams.
It’s almost not necessary. Windows has – in contrast to Linux – a very good and long compatibility guarantee. You can put up any program from 1995 (at least being 32-bit) and it will start and run.
The things GOG is improving are some bugs that occur mostly in games, e.g. something with color palettes in pre-2002 games. But I think every game using DirectX 9 or later will work without any adaptations, even ten years from now.
ReactOS has been around for 20+ years. You can run some old games on it, but it's hardly at the level of WINE and projects based on it.
30 years ^)
