Has anyone tried this on bazzite? Mind sharing if it works? Are there any steps necessary to make it work?

Yep, the problems that require more than the steam flatpak can deliver would of course still be there. But you wouldn’t suddenly be on a depreciated distro without a path forward. Thats what I meant by not totally screwed.

Even if this were to happen, you could easily rebase to Aurora (KDE version of Bluefin) or Fedora Kinoite. You wouldn’t be totally screwed.
