Yep. That is (IMHO) the right (only) answer to actually fix the ‘lying’ problem instead of making it “someone else’s 
problem", although that turns lies into DoS when all you get back from your resolver is unvalidatable answers.

To solve this problem, browser vendors really should implement validation in their stub resolvers. This would have the 
benefit that if validation fails, a useful error message could be presented to the user (e.g., “the website name you 
looked up has been tampered with!”).  Instead, they have chosen to rely on their “trusted recursive resolvers” to not 
lie to them and use agreements rather than code.

This, of course, doesn’t stop the snooping/metadata collection problem.
