That makes sense to me. But if I may ask, are any extensions successfully using non-authentication mode in OpenID already? If so, what useful thing do they offer without a simultaneous identity URL being carried? I'm wondering if leaving out the ID in order to drop authentication from the protocol is the wrong approach. It seems to me like the identifier should always be carried on the protocol, but perhaps with an extra field that says "I don't want proof that my user is this guy... I'm just asking this question about a third party."<br>

<div style="margin: 0px;">I agree with Peter. Tacking things onto particular specs should be avoided to limit proliferation of fields and terms for conceptually similar things. It seems to me that the idea of openid.identity, as the OP-local identifier, would still be applicable in this sense.</div>
