FWIW, <http://www.ietf.org/rfc/rfc2048.txt>, section 2.7 states:

  Media type registrations may not be deleted; media types which are
  no longer believed appropriate for use can be declared OBSOLETE by
  a change to their "intended use" field; such media types will be
  clearly marked in the lists published by IANA.

application/vnd.informix-visionary and application/iges (see the model/
iges registration) seem to be the only types that should be marked
obsolete in the registry and for the former the registration notes:
http://www.iana.org/assignments/media-types/application/vnd.informix-visionary

  Note: This registration is obsolete.  The registration 
  of vnd.visionary replaces this registration.
  Note posted: 05 February 2002

There does not seem to be a similar note for application/iges and the
lists at http://www.iana.org/assignments/media-types/application/ etc.
do not mark these types as obsolete.
