Nux, Overall, I agree that it should be possible to use any other clone as they should be binary compatible.
I don't quite understand your "pass through QA" and "basically RHEL packages" comment. There are already instances of breaking changes in CentOS 8 Stream that didn't make it into RHEL or CentOS non-stream. CentOS Stream is the only one where you *don't* know exactly what you are getting since it is no longer downstream of RHEL: Just one example: https://bugzilla.redhat.com/show_bug.cgi?id=1911827 RHEL 8 versions published (at least that I could find on their errata pages) gdm-3.28.3-34.el8.x86_64.rpm <-- not broken gdm-3.28.3-39.el8.x86_64.rpm <-- not broken CentOS 8 (not stream) versions line up with RHEL as expected: gdm-3.28.3-34.el8.src.rpm 2020-09-17 17:27 <-- not broken gdm-3.28.3-39.el8.src.rpm 2021-01-28 22:09 <-- not broken CentOS 8 Stream versions (hard to track down since all mirrors wipe previous versions now, but this is what I gathered): gdm-3.28.3-34.el8.x86_64.rpm 18-Sep-2020 00:27 <-- not broken gdm-3.28.3-35.el8.x86_64.rpm 02-Dec-2020 23:33 <-- breaking change gdm-3.28.3-37.el8.x86_64.rpm 21-Jan-2021 22:55 <-- broken still gdm-3.28.3-39.el8.x86_64.rpm 29-Jan-2021 05:09 <-- fixed (via a reverted change) Even in this single example, there was a 2-month period where CentOS 8 Stream had a regression and both RHEL and CentOS did not and they skipped the broken versions entirely. The lag is bad for feature updates and version updates, but really good for stability and knowing what you're getting since you are literally building from the same source and won't have instances of reverted commits like the one above.
