Hmmm I guess this kind of makes sense - most distros push Gnome above KDE (probably because it doesn't look like this - where's Tantacrul when you need him?). On the other hand, there's already Kubuntu...

I'm a bit skeptical about immutable distros too. What if I want to install a package that isn't already installed and isn't available as a Flatpak/Snap? Seems like it's going to run in similar issues to everything else that tries to wade upstream against the bad decisions of the existing Linux packaging zeitgeist, e.g. how Nix has to install everything in one root-owned directory because nobody cares about portable installation.
