IMHO...
It is not fair to expect the ACC or APP controllers to work with the rapid increase in traffic levels at DXB without the input from a computerised tool such as Compass or Meastro.
These tools are designed to take distance (on STAR) and performance into account to achieve a (configured) spacing requirement on final.
The same tool would be used by APP and ACC, and thus there would be little or no room for interpretaion or personal artisic impression.
The tool says slow him down, you slow him down, the tool says hold, you hold ....
But hey that is just MHO.
