i don't have an issue with multiple flatpak repos. i'd actually find it very interesting if we went a more decentralized route with flatpak (maybe kde, gnome, mozzila would each have their own repos). but i don't see the point of a distro-specific flatpak when we already have normal packages. compatibility is kind of a non-issue, since you're not supposed to install them elsewhere anyway (unlike flatpaks)

also, i see absolutely no reason to use fedora's flatpak repo on debian given that flathub exists already. you could add it if you want it, but what's the point?
