Correct. You will have to copy-and-paste the issue number into a URL.

For old issues that won't be a possibility, but for new issues it can be
done. E.g.
https://github.com/python/the-knights-who-say-ni/commit/aa82ec527570f8cf1b6ae13037ba6535afe26e5a
links
to the PR that the commit came from and the PR can have a link back to the
referenced issue(s). If you really miss this then someone could always
volunteer to stand up their own web server to server commit history with
the desired functionality, but I don't think this is important enough to
block the migration over as you're now asking that we figure out how to
hack the migrated git history to embed URLs to a non-existent reflector
like hg.python.org/lookup but for issue numbers. If we were also migrating
the issue tracker then it would be possible as they would probably link to
the GitHub issue number.

(And do realize that hg.python.org regularly requires restarts because it
runs out of memory, so that customization comes at a price of maintenance
and Benjamin's time to restart the service.)
