I've been waiting for someone to ask this question. I was planning on
writing an I-D on cookies myself until I studied the state draft and
decided that although the draft itself gives undue emphasis to proxies,
the state header still does what we want. 

My hope is that we can decide on one and only one mechanism for passing
state cookies. If we can accomplish the same thing by a tweak to the
state draft, particularly with respect to examples, then let's ride that
horse. If there's a fatal flaw with the state header, then let's dump it
in favor of a cookie header. But I can't see a good reason to clutter
the standard with both.

OK, I'll bite. How does this differ from the state
draft?  I've scanned it over and it looks to be
doing about the same thing. What am I missing?
