The idea established at the time we introduced Twofish and talked
about MDC.  I suggested to wait with Twofish until we worked out the
MDC stuff.  Anyway, the specs are getting more and more complex, so
we better don't do what I suggested.

Too complicated.  We already have the preferences and issue a
warning when a received message is not encrypted by an algorithm
listed in the preferences.  So we can have the same effect by
setting up the preferences right and issue a warning when the MUST
algorithm 3DES has been used without MDC.
