One could very well envision a network where the routers will act as
DHCP-lite servers, only passing "stateless configuration" like
DNS server, NTP server, .... but NOT allocating IPv6 addresses.

So the next step would be to define NTP server address in RA, web proxy 
address in RA,
SIP server address in RA,.... RA could be extended to pass anything 
that could be a DHCP option.
This is where feature creep happen.
