This argument comes up at least once a cycle and there is a reason we don't do
this. When we EOL a branch all of the infrastructure for running any ci against
it goes away. This means devstack support, job definitions, tempest skip checks,
etc. Leaving the branch around advertises that you can still submit patches to
it which you can't anymore. As a community we've very clearly said that we don't
land any code without ensuring it passes tests first, and we do not maintain any
of the infrastructure for doing that after an EOL.

This distinction does not actually matter, you're still trying to backport code
without the ability to run tests in the gate. The fact that it's part of a
driver doesn't really change anything.
