I think the problem with the previous system was that at some units 'FIS' traffic was identified, becoming 'known traffic' and hence passed 'generic traffic info' but at others they weren't, making them total unknowns and the passing of traffic info 'blurred' the border between FIS and RIS; introduction of Basic and TS was supposed to stop this but obviously hasn't as at some places, traffic requesting basic still needs to be identified to produce a 'known traffic' environment.
Years ago we did try doing this at Farnborough ie not identifying traffic requesting FIS but had to abandon the trial within days because it meant there were too many 'unknowns' and we couldn't clear IFR depatures from either Odiham or Farnborough.
