anotherthing,
I do agree, but sometimes the amount of traffic information given was (is?) a little bit over and above that really necessary as part of the duty of care thing. This confused some people into thinking they would get the same level of info on a FIS from any unit, particularly if given a squawk (even if that was with a non-radar unit like London Info).
Duty of care is one thing, but refusing a RIS and then almost providing one after a FIS has been agreed is what blurs the edges, also I guess some people don't want the Traffic info if they're teaching but got it anyway before. It will be interesting to see how Basic is provided and if a Traffic service might be more readily available than a RIS was.
