That should reduce the airborne holding (and also reduce the cheating that is currently occurring).
That will be an interesting change, given that all those who try to comply with their PTLs get slowed down and all those that charge on in whenever they feel the urge (well outside their PTL, typically) experience far less delays.
Therefore, there becomes an incentive to 'cheat'!
Then, to rub a bit of salt in the wound, the same controller tells you to slow down by 40kts, then vectors you somewhere off the beaten track and once near an IAF says "Request MAX speed down final".
As if an extra 40kts over 5nm is going to make any measurable difference!!
