Those are the only two real ones that I know of. GPG interprets pka-
address, of couse, but it merely "knows about" preferred-email-encoding at pgp.com
(i.e. GPG accepts it, but it is up to the MUA to act on it).
PKA information: http://lists.gnupg.org/pipermail/gnupg-devel/2005-August/022254.html
preferred-email-encoding information: http://www.imc.org/ietf-openpgp/mail-archive/msg08704.html
In the "non-real" category, I've seen "comment" used, but that is an
illegal notation name (it lacks the @ and domain, and is not
registered with the IETF).

That, I couldn't say. It's been my experience that things involving
DNS and OpenPGP have not had particularly good adoption: not that many
people have access to their own DNS, and that acts as a barrier on top
of all the other usual OpenPGP barriers.
