It's ok if you want to create and maintain a Flatpak, but not at the expense of rpm/deb packages, which are never going away.
Personally, I'd rather see a dnf and apt repo for installation/updating so I have one update mechanism on my system. I'd rather avoid the mess of requiring up to four different ways for updating my system: dnf/apt + Snap/Flatpak/AppImage.
