You can, but that completely negates the reasons why you’d want to have a repo system in the first place. You gotta do the legwork to get updates, for example.
And to be explicit about it, zypper, dnf, apt, flatpak all have a specific mechanism to declare repositories and one ‘update’ check will walk them all.
snap does not, and manually doing a one off is useless. AppImage also has no ‘update’ concept, but it’s a more limited use case in general, it’s a worse habit than any repository based approach.
The main reason is that it is completely controlled by Canonical, with no way to add alternative repos.
It’s worth noting you can bypass the repo, and install snaps that you downloaded from some other source - see https://askubuntu.com/questions/1266894/how-can-i-install-a-snap-package-from-a-local-file.
That doesn’t give you a separate “repo,” but it does allow you to install snaps from anywhere.
