They were going to shut it down due to upstream Fedora considering ending 32-bit support. Sticking to upstream wouldn't have helped you avoid that issue.
If Bazzite goes poof overnight, though, that's a major problem. At least Fedora's official spins will continue to receive necessary updates.
The last time a distro tried to do this Ubuntu caved and continued supporting it with an extra repo. Fedora has no chance of winning that argument.
The good news is the incident you're talking about was a change proposal proposed by a single person and never even voted on. It did not survive the comment stage.
