For example, learning default gateways via Router Advertisements provides perfect fate sharing.
I was saving this remark up for when we get to see the "do everything with DHCPv6" draft, but this is as good a time as any:
If we decide to go forward with putting gateway addresses in DHCPv6 to gain administrative control over which gateway a host uses, in my opinion, the only way we can do this without the potential for serious harm is to make require that the same gateway address is both available in DHCPv6 and in RAs. So the DHCP information is more like selection mechanism between gateways in RAs than the authoritative source of the information itself.
And I agree with James' vision: having servers announce their service through a discovery mechanism is more robust than having an outside system enumerate them.
