I'm not convinced there will be a GA SteamOS.
Bazzite also has a much more frequent release cadence which is important for the kernel and Mesa. SteamOS only ships a major version every year.
Steam OS is a rolling release (Arch based) with constant small updates. My Steamdeck has had updates several times this year.
