Yes - fully realise that. However as an example of a "break" in the safety chain it's still a relevant point in my opinion. As has been said before - UK practice is you provide a tower service, or an approach radar service - you can't provide both (unlike the ATCO at Lexington) and it should stay that way. What airac is proposing, albeit it with conditions (until someone calls you and starts badgering you on the ground when vectoring - see how long you can impose those conditions then) is no different, and as such is a break in the chain.
