Hi,
the support should be determined by the Red Hat support, the python3 pacakges have a
lifespan same as rhel8, so 2029. I also have a couple of python3.8 packages on my
ovirt-engine from the 3.8 module, that one is supported until may 2023. So I don't
think this is something that needs to be adressed right now.
