Johnpoz - I did not bring up any government action at all, Yon did.
As the OP, my request stands. I would like to see this, as it is yet another way of securing - not the traffic itself, but in this case, the DNS communication. Does it need it? There has already been attacks that has targeted DNS. And if this gives us one more tool to protect ourselves against problems, is it not a good thing?
No matter what - with a setting in pfSense for this, you could decide yourself if you want to use it. The same way you do with everything else in pfSense :-)
