Yes, and hence my comment on flatpak which turns out is false (that the upstream developer is usually the distributor/packager too). And the other still applies, distro usually adds a specific tag anyway for their refresh. Like that one time xz on rolling debian was named something x.y.z-really-a.b.c.

I think flatpak packagers should also append the specific tag too if that is the case. Like, x.y.z-flatpak-w where w can be the build release version
