That may very well be the official stance, only officially supporting SteamOS in much the same way games used to only officially support a single major distro, often Ubuntu. However, I don’t see it actually stopping you from playing on other Linux systems. The functionality is there at that point. It’s just a matter of making sure you have whatever it depends on from the Deck.
Watch it support the Steam Deck and only the steam deck with no other Linux supported

I mean like valve provides some sort of hardware based attestion so gta v can verify its running on a steam deck.
