I've experimented with the idea of running Debian stable and using flatpaks+appimages on top of it, but I quickly discovered that those formats are really only for GUI apps. That's fine for getting the latest version of Firefox, but you (apparently) can't flatpak, say, your shell. I'm thinking specificially of Fish, which I need the latest version of at all times because it's constantly changing and I've grown used to the latest features added to it. I know there are backports, but those are available at the whim of individual maintainers, and aren't guaranteed to be present. There's also the possibility of running testing or unstable, but it's more straightforward to just install a rolling release distro rather than installing Debian stable and then dist-upgrading. I have great respect for Debian and if I had to use it on the Desktop I would be happy with it, but for me, in 2022, it just makes more sense to use a rolling release distro.
