Ted Lemon answers Dave Crocker:
IMO an essential design benefit in many/most aspects of Internet
technologies is avoiding making any more global assumptions (or
requirements) than essential. "Deferring to the end systems" is a very
broad-based design requirement and it includes minimizing assumptions
about the transit infrastructure.
Sure, but in this case wouldn't deferring to the end systems
argue in favor of allowing end systems to make the decision as
to whether their private information should be exposed?
As I see it, that's not the question here. The question is: Should there be
an RFC that can be used/misused to apply pressure regarding trace fields
etc?
The issue isn't whether person X chooses to add trace fields. The issue is
whether person Y can shout at Z to not add or even mangle trace fields,
with support from a document that looks official, substantial and
authoritative, even though neither Y nor Z understand the nuances of RFC
statuses.
