And then what? Rely on client polling to before you can change any network
parameter, ever? Be forced to run things like VRRP because you can never
change anything on the hosts?

Sure that's the way we do it today in IPv4. But is it the best way? Maybe
in an enterprise, but in a home? What happens when your precious "DHCPv6
server" (home router) gets unplugged by the user and all the hosts are dead
in the water until they decide to send another DHCPv6 request, even though
there are 3 other routers and DHCPv6 servers on the same link?
