Why used DHCPv6 when RA has RDNSS and DNSSL?

IA_PD 'works' (for small values of works) for hosts today.

The upstream interface of a CPE is defined as a host instead of a router.

The big gap in IA_PD is that it doesn't specify how routing is supposed to
work. This is fine if IA_PD happens between routers and all routers have a 
common routing protocol.

For IA_PD to hosts, including CPEs, there is a varity of hacks to install
the prefix in the FIB of the access router.
