If we go down this path, how long before we hear screaming about rogue DHCPv6 servers giving v4-only networks a false v6 path?
Already happened. Good way to install an MITM against any v6-enabled boxes on a v4-only network, been multiple reported uses of that technique.
What's more v4 seem rather less likely to have any countermeasures or methods for detecting this... Back when I worked for a security vendor our endpoint security product specifically disabled ipv6 to address this exposure.
