This was a mistake on my end. I thought I was the owner of the package, but I think I was only the owner of it back in el6. I assume systemd then wasn't depending on it. I saw a PR the other day, assumed it was to me as package owner, and saw no reason to not upgrade since it was long over due. I didn't realise this would break systemd.
Note, it is a bit worrying that systemd depends on this package, which wasn't updated in 5 years, and for which the upstream changelog mostly states "bug fixes".
nirik untagged the package for me. I pinged Zbyszek to coordinate things. I've reverted the commits for f29 and f30 (no updates were issued for these branches yet)
Ironically, this seems to not be the first time this happened either. I see someone else made the exact same mistake in January 2018 and reverted their changes to the package. So let's see if we can fix this now in rawhide so it does not happen again in another year.
