I wonder, does this only refer to the original `extension module' code
that was used by GnuPG or is the concept as a whole not wanted
anymore?  Regarding code simplicity, the module handling code is
contained in Libgcrypt [GnuPG would have to load the external
algorithm implementation and then pass the according functions to

((gpg-key-id . "6F984199")
 (email      . "moritz at")
 (webpage    . ""))
