Hi Andy, This is a useful mechanism, and it hasn't been dropped from the draft. Here is a paragraph in Section 6.2:
A UA should only register against the AOR if it is likely the UA will be answering incoming calls. If the UA is mainly going to be monitoring the status of the MA group calls and taking or joining calls, the UA SHOULD only subscribe to the Appearance Agent and not register against the AOR. However, this approach is probably not described in the non-normative Section 5 description. We should add text there describing it. Is there other normative text you think we should include to describe this option?
