The question is, how long it will be working for?

My Steam account has numerous games in it that supposedly work on macOS, but not really because they shipped 10+ years ago and weren't updated since. Some don't launch at all. Some do, but with various more-or-less-breaking bugs. Of the remaining ones, many don't advertise hi-DPI support so macOS renders them at 1080p instead of 4K.

It desperately needs a stable API for games. Which Proton could provide, except there's also that whole Apple Silicon thing meaning that x64 Windows binaries aren't easily runnable.

Yeah, Apple has been its own worst enemy here. Neither Jobs nor Cook are interested in gaming, so backwards compatibility for games was never a priority.

Linux has always cared about both software preservation and gaming, so it deserves to be the long-term "home" of gaming IMHO, as hacky as it is.

I just wish there was something, anything that could compete with Apple Silicon though :/
