Were that to happen to an official apt repository, you could install from an alternative apt repository. In this case, you can't install from an alternative snap repository. Sure, you can go build a binary yourself and keep it up to date yourself, but that's not really a user-friendly solution in the long term. Your saving grace here is that Ubuntu as a Debian derivative still supports apt repos, but if snaps were to really gain traction that might not always be the case. A desktop version of Ubuntu Core (akin to Fedora Silverblue for flatpak) would not have this luxury.
