I checked and Fedora dropped support for the snap plugin. https://discussion.fedoraproject.org/t/enable-snap-in-gnome-software/76134
These are also the only packages related to gnome-software:
Related Packages
gnome-software-devel
gnome-software-fedora-langpacks
gnome-software-rpm-ostree
From what I remember, their gnome-software already has flatpak support. So all that will be missing is the GUI snap support. Could've been worse.
Yeah, that sucks. I would still want it if I were to use Fedora, as an option.
