Indeed. If any such broken change (eg: that breaks kernel ABI) is pushed to
Stream, that is treated as a serious problem by the RHEL engineering teams.
We have the necessary process in place to QE test changes before they
arrive in CentOS Stream.

I understand this fact alone is not a panacea for all the problems people
are highlighting. But it does seem to cover your use case. From a
regression, stability, ABI, and kernel ABI perspective, it is the goal and
focus of many of us in RHEL Engineering for CentOS Stream to be stable.
