It is important to clarify that this is exactly what I did. I *have* an 
implementation of PEP 580 and it's based on that PR 7909.

I just think that this PR makes sense independently of whether PEP 580 
will be accepted.

That sounds like a bad idea because that would be mixing two issues in 
one PR. If I want to increase my chances of getting PEP 580 and its 
implementation accepted, I shouldn't bring in unrelated changes.

To put it in a different perspective: if somebody else would make a PR 
to one of my projects doing a refactoring and adding new features, I 
would ask them to split it up.
