I've been a Wikimedian for 11 years, but I was on a long break when Phabricator was created and this account is only a few months old. The problem is, my comments from the Bugzilla era are not attached to my current account (see T40227 for an example). I've asked around and been told at IRC that this isn't supposed to happen and the comments/posts should have been merged, assuming that I am using the same email address now. @matmarex has recommended that I file a bug about this, so here I am.

I'm afraid reality bites and that there are no resources anymore to fix the migration script and make it running. Might get declined. :-/
