I share the same concerns:
1) the discussion was fragmented between
zulip/discuss/github/python-dev/python-committers/sprints/pycons and
very difficult to follow, even for interested people (Victor already
posted several links but missed a few others);
2) the progress toward consensus was not clear and the approval came
somewhat unexpectedly (it was mentioned a couple of weeks ago on
and AFAICT no further discussion took place in public forums since

In addition:
1) the PEP contains several factual errors.  I pointed this out during
the core-sprints last year and more recently Berker pointed out some
on GitHub: https://github.com/python/peps/pull/1013 ;
2) the "discussions-to" header of the PEP points to the zulip stream.
The stream has not been active for 6 months (it got a few new messages
today, the previous activity was in Dec 2018);
3) most of the discussions linked by Victor happened last year.
Unless I missed some, the only discussions happened this year are the
two on Discuss from February (with 3 messages each from a total of 5
authors), and the python-dev thread from March (with 12 messages from
7 authors).  One of the two Discuss threads was a inquiry about the
process (https://discuss.python.org/t/move-pep-581-discussion/873);
4) Berker is/was writing a competing PEP, in order to address the
problems of PEP 581 more effectively since his comments on GitHub
haven't been addressed;
5) next week a student is supposed to start working for the PSF on
b.p.o and Roundup as part of Google Summer of Code
6) PEP 8016 says "The council should look for ways to use these powers
as little as possible. Instead of voting, it's better to seek
consensus. Instead of ruling on individual PEPs, it's better to define
a standard process for PEP decision making.";

To summarize, I feel the approval of this PEP is premature and that
consensus was reached in a way that wasn't very transparent, without
considering some of the concerns.
(This might also be a symptom of a wider problem caused by the
fragmentation of the discussions between the old MLs, discuss, zulip,
IRC, GitHub PRs and issues, and IRL meetings, but this is a separate
