It seems EPEL doesn't use a repoclosure test when pushing from testing
to stable.
Let me just take one simple example : I recently asked a pkg to be built
for epel 8 (see https://bugzilla.redhat.com/show_bug.cgi?id=1755787)

So that package itself was able to be built, and despite the fact that
it was mentioned that it has some Requires: issues (see two other
reports in the original one), it was still pushed from -testing to
stable , so actually you can see it :

Available Packages

But it's not installable (obviously) :
Problem: conflicting requests
  - nothing provides kid3-common needed by lollypop-
  - nothing provides python3-pylast needed by lollypop-

Stephen (smooge) would probably be able to comment if that would be
possible for Epel to have some gating from -testing to stable (like a
simple repoclosure test) to see if packages pushed to stable can be
installable (and so satisfied deps in stable repo too)
