I think there are other breaking changes that may also affect users,
e.g. revoking create privs from everyone except the DB owner on the
public schema (which probably has the most impact), removing exclusive
backup mode, etc. These are covered in the "breaking changes" portion of
the release notes.

The PG15 documentation also makes this pretty clear:

https://www.postgresql.org/docs/devel/plpython-python23.html

Perhaps in the GA release we add something to the announcement, but the
release announcement is geared more towards "what's new" instead of
"what's breaking".

Thanks,
