More than any other comment, this one seems to sum up the real opposition to
publication of this document:

  This document conflicts with my political agenda, so it cannot be allowed to
  be published.

It's a well-written discussion of issues that need to be taken into account
when considering header encryption.  Taking the "lalalalala-I'm-not-listening-
lalalala" approach won't make these issues go away, it just means that they'll
come and bite implementers and deployers of header-encryption protocols
because the document that would have discussed them in order to allow them to
be addressed at the design stage before they became a problem was suppressed.

May I instead rephrase the above objection slightly to:

  I also support publication of draft-ietf-tsvwg-transport-encrypt.  This
  document points out real issues that need to be taken into consideration
  when encrypting headers, and not publishing it will harm future protocol
  development.

Peter.
