Just ask the SIP crowd about their experiences with SIP proxies
dropping every new option by default even the ones meant to be
passed on transparently. Aka: the issue of middleboxes isn't
limited to IP land.

Ultimately its human nature that operators who can act as middle men
have a tendency to misbehave, however good intentioned it may be.
See my last mail on encryption.
