The requirement you cited is a MUST-level requirement, it is not a pre-
ference. You are arguing that such a crawler cannot be implemented with-
out violating the protocol. I do not think that is a reasonable reading
and certainly not what I had in mind when reviewing the document as part
of my Last Call reviews. I also note that your argument would go both
ways; if

  user agent -> user configured intermediary -> origin server

violates the protocol, then it seems pretty clear that

  user agent -> CDN -> origin server

would also violate the protocol, as that is not a true end-to-end path
either.
