And ELN is different here because it has a rebuild number in the dist
tag, so it is much easier to do rebuilds (bump the rebuild number, do
the required builds, done).

We have walked back ABI versions in Fedora rawhide in the past and know
how to do it, but it requires per-package dist-git upgrades for fresh
NVRs.

Thanks,
