Sure it is relevant, until one IFR flight has cleared the part of the
airspace relevant to his departure the second IFR flight cannot be
released for takeoff.

until the IFR arrival he's waiting for has either cancelled IFR or has
landed.

IFR or VFR is not relavant.


He's right, the controller is not going to issue taxi and hold to a flight
that is going to have to wait 10 minutes to pick up clearance. If they are
ready to go, they are ready to go.
