While Valve only officially supports 3 devices, it is possible to install its image on any PC (or just run Steam on Linux). But quite a few Steam users don’t realise that.
Also, Valve only officially supports Ubuntu LTS desktop (Gnome). And their own OS of course. Yes, despite having the Steam runtime. The only thing this means is that support agents will say “but did you try installing Ubuntu?”.

I guess that means steam support doesn’t end up being general Linux support.
