Just out of interest: how?

Well, I could live with the buildsys adding it. But I'd prefer not to go
with special patches, thus I'd would be best if patches that make this
work get integrated directly into mock.

But:

Nobody said that we need to use it everywhere in Fedora-only packages.
But it should be allowed there. That afaics should be acceptable

A special repotag macro has one benefit (and that's why I currently
think it's the best solution): the spec file could be exchanged easily
with other repos. Just define the individual repotag and rebuild one
spec file in different repos (dag, CentOS Extras, EPEL, <private repos>,
...).
