BL, you know I'm just an over-opinionated Aussie wandering the world.

SMB, got ya! (told you I'm a little slow at times). Positioning traffic (or priority/emergency traffic) coming to us high can increase workload a little, but having a creative TMA bod can really make life easy. Luckily, as a great deal of our positioning flights are from the surrounding London TMA airfields, they don't really get the chance to get high enough to start mixing it up with stack traffic, or we get co-ord early and "book" minimum stack for them. But sometimes, if it's all going horribly wrong, the hold is the best place for them.
