Comment(by iang):

 I have successfully tested it.  I've attached the controller script I
 used, which attaches user streams to a succession of non-exit circuits,
 some of which support optimistic data and some which do not, before
 finally connecting it to an exit circuit, which succeeds.

 I might suggest applying the attached diff, to make the log message a
 little more useful.
