Indeed, it's difficult to keep up with all the threads :)

To summarize, are these alternatives correct?
1) we don't rewrite: users will see #NNNN, issue #NNNN, etc, but those
will just be plain text and won't like anywhere.  This might cause
minor confusions to users (they can see they are not links to GH
issues/PRs, but they might not know what they refer to).  Even if
eventually we might have enough PRs that the numbers will start
overlapping, there shouldn't be any wrong link (the link are not
created retroactively, unless GH changes in the future).  We will
still use bpo-NNNN moving forward to avoid ambiguity, even thought it
will be inconsistent with the old ids.
2) we rewrite: users will see bpo-NNNN on old commit messages and they
will know that they are not links to GH issues/PRs, and they might
know/guess that bpo refers to bugs.python.org.  These will still be
plain text and won't link to bpo (unless GH allows us to do it in the
future).  We will still use bpo-NNNN moving forward, and this will be
consistent with the rewritten history and unambiguous with PRs ids.
