This reminds me of a small discussion we had some years ago when i targeted
this for the sake of completeness of ASS (see
<http://archives.postgresql.org/pgsql-patches/2006-06/msg00021.php>).
I didn't follow the previous discussions about EXTENSION very closely, but
to amend the idea made in the mentioned thread, couldn't we just invent a
facility to move classes of objects belonging to an extension, only?
