Admittedly for their specific use case proton goes way beyond wine
Actually no; proton is almost entirely wine. It's really like 90% the community (wine contributors over a span of three decades), 8% a german developer on his free time (the one that implemented dxvk, which is 99% of the magic in proton), and like 2% valve (and mostly because they started to pay said german dev).
This is the culmination of 30 years of community contributions, almost entirely by volunteers, without profit motive. Valve did very little beyond adding a bubblewrap-based sandbox to improve reliability a bit - though they did speed up things those past few years, admittedly.
