There are plenty of solutions out there that are debian or RHEL only, it will work on other distributions but they aren’t supported. If you have a problem, the answer will be “Use Debian” or “Use RHEL”. And there is nothing wrong with that answer.
I appreciate they are trying to support users who are veering away from the recs, but that’s on them. As is not just using flatpak - which I personally don’t like using, but absolutely use for work/commercial software.
