This request for only those not at the F2F to add to the hum has gone a bit off the rails. 

For those not in the room there was discussion that the draft needed a method to deal with:
- Multiple AS
- Supporting the PoP specs
- stopping clients or other interceptors of the token from introspecting it.

Justin stated that his implementation already had a number of those features. 

I offered to help get those into the spec as part of my support for making this a WG item. 

Yes if AS and RS are monolithic and there is only one software vendor, then this is not needed. 

On the other hand there is evidence that is not the case.
