Don't worry about python3.7 and python3.8 as it is likely they will continue to function as long as 3.6 and 3.9 are happy. This would reduce the size of the testing matrix. We can always reevaluate if problems for 3.7 and 3.8 occur.

That said I have a strong suspicion that if OpenStack runs on 3.6 and 3.9 that it should just work on 3.8 as well. And as I mentioned if we prove that wrong through experience we can always fix 3.8 and go back to explicitly testing it. I don't think this particular change is super critical, but I know some people were concerned about the number of pythons that would need testing.

Yeah, adding 3.10 as non-voting is a good idea like we did for py3.9.

Anyways TC is going to discuss these in today's TC meeting, please join us there to conclude things.
