I do not have RFCs to counter that, but my interpretation is a bit
different.  I see that section of 4861 as traditionally applied to 
*hosts*, while IA_PD traditionally is a *router* function, so out of 
scope for the "host part" of 4861.

Now this gets all muddled together when you have a router that also 
wants an address for itself (= acting as a host for that purpose) or 
a host that wants a prefix (= serving as a router for that prefix).

Conceptually, still, "address for me" is a fairly independent thing
from "prefix for something I serve as a router"...  and 4861/O/M only
seem to cover the "address for me" part.
