I don’t think anyone really wants to move PD into RA. I think that would be inappropriate, personally.

Without moving the PD functionality into RA, then, I would say that the current situation is fine.

CPE should ask for PD if it wants a prefix.
It should deal with one of five possible results in response:

	1.	No response
	2.	Denial
	3.	Requested prefix size granted
	4.	Longer prefix (smaller net block) granted
	5.	Shorter prefix (larger net block) granted

Nobody has yet made a good case for why this behavior is problematic.
