And "Windows" games run better in Linux/Proton. It's more like a re-implementation of a feature set, right? Like, I could see devs targeting Proton as the primary target sometime in the future. That's kinda how some multiplatform systems work already, going all the way back (at least) to "Java apps" in the 90s. (I can't think of any older examples off the dome, but I only got into coding in a big way in the 00s, so I'm not confident.)
