Great idea - would make GMC a doddle for the ATCOs, but a teensy weensy bit busier for the pilots!! Just say "Cleared to the holding point 27R, providing your own separation" for departures, and "Stand xxx, providing your own separation" to the landers and sit back and watch it happen.
A pilot made a similar comment on here some time ago. He went away with the screaming hysterical laughter of Roger Dee, Charlie Park, Ronnie Radar and other notables ringing in his ears!!
