How does rebasing work? If Universal Blue were to shutdown and Bazzite/Bluefin/Aurora were to suddenly stop development and updates, could I rebase to any other atomic distro without losing my files/apps and continue to get updates there? Using the same DE (since I heard there are some issues, fixable, but annoying)
Or is it just a way to swap to a new distro while still being able to swap back to a backup of your old one if you need to?
(It doesn’t matter if them shutting down is illogical, being able to move provides a sense of security.)

This should answer most, if not all of your questions.
It’s important to remember, that you should rebase to the same DE to avoid issues. Although there shouldn’t be any data loss when rebasing, a backup of your files is recommended.
Edit: Forgot to write, that these principles apply to all atomic distros. But depending on the distro you’re using, the rebasing commands might be slightly different. So always look on the documentation of your distro.
