you do realize that not even 0.001% of people use that, right?
DNS has to be encrypted by default for everyone. As in client -> recursor. Without any 3rd party software.
do the same for the fucking DNS protocol, which is clear-text, it's the weapon of choice for all surveillance/censorship freaks and nobody cares about. And by 'nobody' I am not referring to actual random Joe users, but you - the fucking mastermind developers who create stuff that nobody cares about, hosted on .io domains just because it is cool and looks like some start-up that's about the be the next big thing.
Please fix the DNS crap and you will be remembered in the history of those who gave a damn about totally broken stuff.
