I don't use CentOS Stream, I use RHEL. I use RHEL to develop software

binary compatibility, and specifically kernel ABI compatibility, then
the users of the software packages we develop can continue to use them.
If not, they can't. Simple as that. So please don't push rolling kernel
updates to Stream that break the kernel ABI.

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.

Rolling kernel updates are going to kill all the traditional HPC clusters. Almost 25% of the TOP 500 HPC clusters run CentOS. See https://www.top500.org/statistics/list/
