Those are good points. We were discussing with the RDO team on the start
of Yoga cycle itself whether to move to CentOS Stream9  or not.

Yes, there is a clear confusion on what is stable or not in CentOS Stream distro.
Like other distro has, is there any document we as TC can refer to in the future on
checking if the CentOS Stream *X* version is stable/LTS or not? I cannot find it
for CentOS Stream 8 also, is that stable or LTS? 

If we have such official documentation or announcement  in RDO community
then we can avoid such situations in future where we get to know the distro
version stability well before trying it in OpenStack testing?
