Not sure about "the Appkit port".

If you mean Emacs 22 Carbon+Appkit port, then I maintain this just
because I'm using it in our classroom.

If you mean Emacs 23 Mac port, see the following message in
http://lists.gnu.org/archive/html/emacs-devel/2010-06/msg00148.html

FWIW, half of applications that are bundled with Mac OS X 10.6 are
linked with the Carbon framework.
