It could still help you
They identify you, then if you stray into heathrow, gatwick or some danger area then you'll be warned. Whilst you haven't done that yet, the service didn't help. However, that day you get the bearing ever so slightly wrong, or the wind is different, or your busy looking at something or other is the day that it will help.
Also, if you have an egine failure and perform an emergency landing they will vector helicopters and emergency services to you.
Finally if you have conflicting traffic, and a real chance of collision, then you will be informed of it but obviously look out is still your problem.
