"Acksherly Doc 4444 says a lot more than that; it says you may provide identified traffic with a service very similar to what we presently call RAS/what will be called de-confliction service! "
That is what they seem to provide in France. An FIS but it's obvious they have you on radar and they give you traffic info with possible avoidance directions as necessary.
Why can't the UK do the same pragmatic approach?
The whole thing seems bound up with tight rules and it also looks like there are rules on whether an ATCO of a certain grade is allowed to see a radar screen.
