Comment (by asn):

 OK I have a new branch in `bug28634`:
 https://github.com/torproject/tor/pull/635
 and I also updated the spec PR:
 https://github.com/torproject/torspec/pull/72

 This branch takes the simplistic approach of only trying to make the
 initial circuit setup cell sequence blend in with general circuits. I find
 this to be more sophisticated than a look-like-nothing and it also has
 minimal overhead.

 Also, this is a fine start if we want to build this into a more advanced
 machine. We can just create new states that handle obfuscation after the
 initial circuit setup sequence.
