A while ago I proposed code owners for the packaging files. We tried this but didn't work in our setup. It turns out that those mentioned as owners need permissions on the repository. In our case the packaging team (not individual members) has no permission.
There are 3 options:
1) Remove the file since it doesn't work
2) Create a packaging-core group with the intersection of both groups
3) Give @theforeman/packaging permissions on core
Personally I'd really like us to work together better and think this could reduce our packaging issues but have no preference between 2 or 3.
