Valve has already sent support for the new Steam Controller upstream: https://www.phoronix.com/news/New-Steam-Controller-SDL


Those companies aren’t exactly releasing consumer-facing distro’s, though.
True, but would one want to have a BigTech labels on their Linux distribution? Wouldn’t that kind of miss the point and bring us back to e.g. ChromeBooks?
Maybe. As it stands Valve is rather open with their implementation, but who’s to say it will remain indefinitely so.
I do get the desire, though. I’ve gone to Bazzite and Fedora and – even though it’s a lot better than just a year ago – it still requires some commandline tweaking. It isn’t entirely smooth sailing yet.
Will SteamOS be? I do have some doubts.
FWIW been using SteamOS on the SteamDeck for ~3 years now and from gaming to tinkering, no major problems. Never had to tinker hard or re-install. A couple of time it didn’t suspend properly or I had to hold power button of to force a shutdown but that’s about it.
I doubt Valve would back of from the openness because that’s their one single advantage.
