Just a minor point: Is it worth adding (either in section 4.1 or 6) that a temp-gruu might not be as anonymous as you might hope? An observer using RFC 3680 (reg-event) with gruu extensions would be able to correlate temp-gruus with AoRs and contacts, should they be so authorised.
There is some text in RFC 3680 warning of the risks of reg-event, but that is probably of more direct interest to registrar authors. A reminder of the risk in this document might highlight it for UA authors, so that they can consider the wider implications.
