Draft updated PEP is posted at https://github.com/python/peps/pull/315

I ended up proposing a replacement PEP to supersede 394, rather than
proposing changes to 394 itself.

It's essentially a PEP 394 superset that allows for a few more
"endorsed" configurations for redistributors (essentially saying
"Arch's move was ~5 years ahead of its time"), with more of an
emphasis on "What might a post-2020 sans-Python-2 platform release
look like?"

Structurally, it clearly separates the recommendations into 3 distinct
sets (ad hoc scripting, app development, and platform publication)

I'm not sure how you ended up receiving it, unless there's something
odd going on with the configuration of linux-sig-owner in the mail
server.

Cheers,
Nick.
