Re: [Rats] IANA pre-RFC code points

OK. There’s a PR for OIDs and URIs now. It also does pre-assignment for the profile claim so it can be included. 

Ned, please advice on next step here.
 - Is Profile stable enough for reassignment?
 - If so, do we have to issue an -09 draft?

Please, no more request for claims for pre-assignment so we can get this done.
