I would like to point out that in IPv4 we have ICMP Router Advertisement messages. I have never seen them used on a production network. I know one of the worries is security, that a compromised host could send out advertisements, drawing traffic to it that it can then snoop and pass on to the real gateway.
DHCP and ARP face the same issue. That's why "one host per subnet" is so appealing.
