Brett, sorry I wasn't more explicit about my concerns here. I added you and Nick to this issue and to its PR not primarily to do do code review but because I think it brings up issues that I believe haven't been dealt with before in our evolving environment and may need guidance from the Steering Council and the PyPA, both of which you two have been involved in. The PR is about defining new platform tags, something which has potential impact across both CPython development (it can affect how Python itself is built) and across the packaging realm (as any packaging tool like, presumably, pip and wheel and others are potentially affected).  This also is relevant to recent discussions about the roles of PyPA and CPython development.  Because it has the portential to impact and require changes across the board, we need to make sure that proposed changes like this get adequate review and consensus across the board.  I'm not exactly sure how that should work so I think it's something that is worth clarifying.  AIX is already a supported platform, at least on best effort basis thanks in large part to the efforts of non-core developers like Michael here (and thank you, Michael). So, in this case, the impact is probably most on the PyPA side so I think there needs to be their explicit involvement.  But, for example, there is a risk of a similar PR adding new platform support without adequate review which could have a major long-term impact on CPython maintenance and support (and such things have happened in the past).  Perhaps we need to formulate an explicit policy about approval of changes to cpython that affect platform support and thus packaging.
