However, passing None as the default to ui.config yields warnings about mismatched default values, which is why I ended up registering the flag with None as its default... that might be wrong,

That seems fine.

Using hasconfig() is also fine.

> Unrelated: git email reviews allow editing a patch before sending it via email, so you can add some review-only text in it (look for "timely commentary" on this page: https://git-scm.com/docs/git-format-patch#_discussion). Is there some similar convention for mercurial patch emails? Or are we supposed to just reply to the patch email right away like I'm doing right now?

I prefer including that in commit message. You could edit a mbox file to insert
commentary before the "# HG changeset patch" header, but it seems unnecessarily
