I was making the point on what people are ok with when it comes to DNS 
servers, but I can agree that we should work on making DNS server setup 
more secure and capabilities more known. I believe there is work in 
dnsop on that at the moment (draft-sah-resolver-information).

There are ways to protect against rouge RA/DHCP on network devices, but 
I agree it is an attack vector.
