my intention certainly wasn't to try to exclude anybody. for me, it's the practical matter of the PR UI being more effective than a mailing list thread (in this case referring to a gist), and that we can track proposals easier and link to them from issues (in that same repo) and other PyPA docs.
also, to be clear, this isn't about thinking PyPA would sidestep the PEP approval process all together. It's about managing drafts, reviews and updates into that process.
certainly, this isn't my decision alone to make this change... just stating my preference, and hoping to get others to agree. Part of my motivation for bringing it up, was do due to trying write a "PyPA Roadmap" recently for
pypa.io, and wanting it to be easier to track and link to ideas that people are coming up with (ideas that don't immediately start as draft PEPs)
