IMHO the discussions on the PEP 572 became a mess because nobody
wanted to moderate the discussion. I asked on python-committers how to
calm down the discussion, but no action has been taken and the flow of
emails didn't stop.

FWIW, I think this is a key thing— Mailing lists are not easily moderatable. There’s no way to pause discussion, redirect, etc besides generating *more* email (and the tooling to do it is lackluster, it’s pretty much just asking people to do something, and hope everyone complies). Fracturing the discussion amongst multiple repos is one way of handling that, another option is better tooling for moderation.
