my client (Turnpike) will handle incoming message/external-body but does
not generate it

        https://en.wikipedia.org/wiki/Turnpike_(software)

I still use this software every day (see headers), but I haven't seen an
example of this MIME type for many years (the IETF used to use it for
their notifications of new RFCs and drafts)

BTW: there are surely other WGs where any MIME extension work (if you
want to add content hashes perhaps, to assist in abuse prevention) will
be better handled. If you just want to encourage the use of this MIME
type then I doubt it matters where you do it !
