I would like to bring this issue back on topic as this about how to expose PEP 523 support in Python 3.8, not whether Fabio should be using a different approach when he has been something sanctioned in an accepted PEP and was previously doable that was (accidentally) taken away from him. If people want to do a separate PEP to roll back PEP 523 that's fine, but until that occurs I think we should move forward with the fact that PEP 523 is active.
