Keeping such a community governance split from happening was one of my key goals in volunteering for the inaugural SC - packaging and the interpreter’s import system and interface stability guarantees are too closely entwined for complete independence to be feasible, and securing Guido’s original standing BDFL delegation to specific PyPA contibutors/supporters genuinely helped resolve some of the political conflicts in the packaging community (as well as providing clarity for the wider Python community), so I wanted to see that continue into the SC era.
The enfranchisement side of the question has definitely been an ongoing concern though, mitigated by the fact that there are several folks that are both PyPA developers and CPython core devs, as well as by the mechanics of the standing delegation process. SC interest in improving the management of that broader scope of responsibility would definitely be appreciated.
