Bazzite is a part of the Universal Blue family, which is more of a repackaging of Fedora Atomic.
I'm a fan of my Steam Deck and SteamOS, but I'd like that experience to eventually be available via community supported distros, which Valve/Igalia can rebase from, and instead focus on Proton.
Bazzite is the closest to that that we have so far.
SteamOS is Arch based, and can be replicated on Arch by installing Steam if you don't care for the "game console" UI trimmings. Based on another comment thread about past stupid proposals on Fedora, Arch seems like a much more reliable base than Fedora.
