As Marcin posted, the plan in RDO is to support both CentOS Stream 8 and
CentOS Stream 9 in Yoga. This is how we have managed previous major CentOS
version upgrades in the past providing support for both releases in an
OpenStack version to ease the upgrade so I'd like to keep yoga working on
py3.6 included in CS8 and CS9.

May it be possible to keep py3.6 jobs to make sure patches are not
introducing py3.8-only features that would break deployment in CS8?

Just for some background, we started adding  'python_requires'  in
