I think it would be nice to add a little advice on how to manage the state, but it's up to the authors to do this or not. This discussion is getting a bit old. 

I do have a question which I don't see addressed (no pun intended) in the draft.  The text only refers to THE first-hop router on the network.  If there are multiple routers on the network which can respond to router solicitations, do they act independently in providing prefixes to the requesting hosts?  If so, how do they (or do they) guarantee uniqueness?  If not, do they need to share any additional state?
