From what I understand offset flying has been available as an option on NAT tracks for some time, and the NAT authorities, far from "seeing the light" were actually bitching last August (nearly a year ago) about the lack of take-up from transatlantic crews, only one in 10 of whom were bothering to offset when two alternative tracks - 1nm and 2nm to the right - were open and available. These stats were circulated within NATS and through other outlets.

Of course, if everybody offsets by the same amount, there's no point in doing it! It just moves the problem a mile or two to the right.
(Offsetting to the right will protect against opposite direction traffic but not same direction)
