Point taken. Good find with gdm, wonder if there are others.
I'm hoping this kind of problems disappear in time as the machine gets
"oiled" better.
What I wanted to underline is that the situation is sort of like this:
Updates -> QA -> Stream -> RHEL
Might be then worth going for supporting "EL8" and by that include any
of Rocky, Alma, OtherClone etc.

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.

Nathan,
So with Stream you'll be getting basically RHEL packages, after they
pass through QA and before it lands in actual RHEL.
In fact, it's only with CentOS that you know exactly what you are
getting. The clones will undoubtedly lag behind at various times, just
like old CentOS did.
However, this needn't be a problem, if all works as planned, you
should
be able to use RockyLinux or any other clone's packages on CentOS
Stream, since they should be binary compatible.

CentOS Stream could be fine or a disaster, and it is hard to tell:
"a
rolling preview of future RHEL kernels and features." as the RedHat
CTO
said seems to imply cloudstack might run into a lot more issues due
to
the squishy nature of kernel releases, kvm/libvirt, etc. I don't
think
it will be unusable, but it will be hard to say what is supported.
(E.g.
what version is "Centos 8 Stream"? Stuff can change out from under

pretty quickly in that paradigm. Even rolling distros like Debian
have
point releases.
