Largely package / feature support. RHEL is clearly betting the farm on
OpenShift / OKD. Which is fine, but the decision to depreciate / remove
things in RHEL (spice qxl, gluster) are also reflected in CentOS Stream.
Even if you want to backport things to Stream as rebuilds of old /
existing packages to re-enable some of those features you are now
fighting a moving target. Would be easier to target RHEL than Stream if
that is the goal.
Fedora has no such depreciation of features, has a larger package
library, and more room to grow oVirt into something more compelling. If
the decision is made to base on CentOS Stream, might aa well base on
Fedora instead as neither is going to have the full enterprise life
cycle of RHEL and both will break things here and there. At least with
Fedora you don't have to maintain an ever growing list of things to
maintain to keep oVirt's feature set in tact.
In short, targeting RHEL over Fedora made sense when CentOS existed as a
downstream rebuild, when RHV was a product still, and when the entire
oVirt feature set was supported by RHEL. None of those things are true
today, and instead of targeting a psuedo RHEL where you still have to
maintain a bunch of extra depreciated packages without the lifecycle
commitment, Fedora makes more sense to me.
My two cents anyways, for my use case not having Gluster or spice is a
breaking change. While i wouldn't mind contributing to oVirt here and
there as needed if someone picks up the pieces, i don't have the
resources to also maintain the growing list of depreciated / cut
features in the base OS.

I'm curious, why do you think Fedora rebase is necessary to keep oVirt
alive?
We tried that for years and gave up as Fedora is moving way too fast to
keep oVirt aligned with the changes.
CentOS Stream 9 has EOL is estimated to be 2027 according to
https://centos.org/stream9/ and I expect CentOS Stream 10 to show up by
the end of this summer according to
https://www.phoronix.com/news/CentOS-Stream-10-Start (well, official GA
will be in a year but I guess people can start playing with it much
earlier).
