can someone please tell me if I understood correctly the packaging guidelines regarding packages being retired after a rename [1]?

Upstream has changed between minor releases how the source code is packaged. Instead of multiple source tarballs there is only one tarball that is used to generate the same packages as before; so the update is for all branches.

Should I run "fedpkg retire <explanation>" in each branch that is going to be obsolete by the new packages AFTER the new packages [2] hit stable, right?
