I do not understand, you want to keep the ports you were maintainer?
If you're listed as Packager does not mean you have kept the port. For example, I keep the original packager for opt/chromium: Tadeusz Sosnierz, and this person has never been part of opt Maintainers.

IMHO to obtain a more accurate list, you should get a git checkout when you were a maintainer, and compare each port with the current one.
Anyway, I think to do this better, you should inform the affected maintainers. So in your list you could include a reference to the current maintainer for each port that you want to retrieve.

When you left the contrib I adopted some of your ports. If you want, you can keep 'amsn, atitvout feedparser, snownews and svn2cl'.
I just hope that your new life as a maintainer be more durable and we do not have to readopt your ports again ;D
