ANSA,
Still no one from centre has answered why Dubai cannot control its own holds. If there was an appropriate stack for the active runway with a timing pattern, from the hold to the runway, it would solve just about all of the problems you describe.
Centre could manage the aircraft through their airspace, deconflicted by altitude to the hold. Then Dubai could pick off the aircraft as required and finally finesse the aircraft after they have left the hold to guarantee the spacing on final to fit in the departures.
Dubai wouldn't need a 'robo-coordinator' and centre's workload would be massively reduced. If the procedures in force are not optimum; change them. They should be simple enough that even the lowest common denominator can operate them. Don't blame the coordinator until the procedures make sense. I know there is a bit of history between various individuals on both sides of the divide but surely everyone can rise above it. If we can sort the airspace out it will benefit Centre Controllers, Terminal Controllers and Pilots alike!
