I second Bazzite. It's been a phenomenal experience on my laptop.
Interestingly, I was messing with BoxBuddy a week or two ago, and looking at what distroboxes were available to install, and there's a SteamOS container on there. Not sure if it's official or what, but I was able to run games on it (though absolutely unnecessary).
Pretty solid on desktop. Most issues i have are upstteam and not bazzite related. Main annoying thing is you can't install fedora packages and have to mainly rely on appimages and flatpaks
I just think it'd be neat to have a gaming Linux distro, made by a company that distributes games. Maybe it will be a standard distro for game developers to test their games.
No system management. A set once and forget it system, ala console style, but with the potential of off the shelf high power components for PC games on the living room is a quality proposition.
Sure, but the support, both technical and reputational that a steam OS compatible machine brings would steer the market for more accessible and purpose made components. Bazzite is awesome and my daily driver, but it doesn't have the fancy endorsement of Valve, the owner of the largest game store in the world today.
