The safest option to do that is a DHCPv4 option that says 'no IPv4 service
here, go away'.

Any network that has IPv4 production traffic already has to protect against
rogue DHCPv4 servers. 

Of course, a DHCPv4 option conflicts with the goal of some people to have
no IPv4 related infrastructure at all.
