I agree that this could be useful.  Nothing stops anyone from making their CPE in active mode.  I assume that most people would make one implementation that can be configured in either mode, but maybe I assume too much.

I hope I get this right because I don't have the comment resolution in front of me, but I believe we adopted the following:
 - Add another bit to distinguish the following cases:
   a) The sender has received and processed the configuration of its peer, and decided it does not wish to accept it
   b) The sender has not yet finished processing the configuration of its peer
   c) The sender has not received the configuration of its peer

Currently, we just distinguish between (a) and (c).  

We had a discussion about adding more error indications (rather than just a generic I don't like it), but we couldn't come up with a list or standard set of reasons to explain the rejection.  So the "rejected for whatever reason" was as good as anything else we came up with.
