It would introduce more security and transparency and address many of the non-technical concerns around DNS filtering. There could even be a mechanism in which the user picks a specialized provider of filtering rules, and then tells whatever resolver they are using to apply those rules, all through authenticated secure communication.

More generally speaking, I think that it would be very beneficial to Internet end-users if the discussion around [DNS] filtering in the technical community moved from "is filtering good or evil?" to "filtering is a fact of life, how can we make it work better?".
