Dude, shut up. SteamOS is Wayland. Only the Deck shell (and KDE desktop mode used to) uses X in XWayland mode. But all games run on Wayland. Without Steam massive push of Proton we wouldn't have the booming Linux gaming scene that we have now. You fucking lot are insufferable, this is why nobody likes Wayland. It is super good, massively better than it was before. Can it be better? Yes, sure. But shut up and let people cook, would you? Recognize a good thing when it happens. Just because it isn't perfect yet doesn't mean it isn't good.
EDIT: You can downvote all you want, that doesn't change the fact that SteamOS is Wayland, it runs the Gamescope compositor. You asked to be corrected, here I'm correcting you.
