Everything prior to ".module" should be unique, identifiable, and
identical between RHEL and CentOS. MBS whacks %dist to add MBS
information at the end. So there is some mapping. Additionally, when
the RPMs are imported from RHEL into CentOS, the original NVR is
present as a tag. Ignoring transmodrifier remapping modulemd commits
between RHEL and CentOS, you have enough baseline references to be
able to connect the dots because the RHEL dist-git shorthash is
present in the import tag, which would exist in the imported modulemd
before transmodification.

That process could be automated, but I was never particularly
motivated to do it because of the historical attitude around providing
errata for CentOS users like Fedora users get.
