As discussed in the meeting tuesday, deprecation is a tricky subject for
formats with stored data (as distinguished from on-the-wire network
traffic).  people have archives of encrypted data that may still use
this cipher.

The sense of the room in Yokohama was to deprecate as much as possible,
and encourage a limited, sensible set of algorithms for message creation
and signing.  But sensible implementations will likely continue to allow
decryption of these ciphers for years to come.
