Hello HD,
I understand what you're saying. I was just trying to extend the analogy of when SSR was first introduced which obviated the need for a 30 degree identification turn and, later on, requests for passing levels and so on.
It will be interesting to see how the non-NATS units get on when their legacy radar equipment is replaced by the likes of the ASR10 and the Thales thing (sorry, can't remember its name).
