Nick Coghlan added the comment: Aye, this is the issue for making the API public, so it will stay open until PEP 432 is actually accepted. We switched to the pre-implement-changes-as-an-internal-CPython-refactoring approach after we/I realised there was no feasible way to develop and maintain

Nick Coghlan added the comment: As far as the specific 5 phase vs 2 steps goes, the two steps in PEP 432 terms are the "Pre-Initialized -> Initializing" transition and the "Initializing -> Initialized" transition. What Gregory is talking about is a potentially good way to organise the second
