Hopefully wrapping this thread up ... I've just posted a -25 revision 
that contains a new paragraph which I think now has references to all of 
the mentioned documents.

    The concept of a protocol's "wire image" is described in RFC 8546
    [54], which describes how TCP's cleartext headers expose more
    metadata to nodes on the path than is strictly required to route the
    packets to their destination.  On-path adversaries may be able to
    leverage this metadata.  Lessons learned in this respect from TCP
    have been applied in the design of newer transports like QUIC [58].
    Additionally, based partly on experiences with TCP and its
    extensions, there are considerations that might be applicable for
    future TCP extensions and other transports that the IETF has
    documented in RFC 9065 [59], along with IAB recommendations in RFC
    8558 [56] and [66].

(where [66] is the IAB use-it-or-lose-it I-D)

I think this should be good for Martin to move ahead with it if captures 
the right sense of what everyone has been suggesting to add.
