Pvo brought up a good use case for naming a little while ago: Migrations.

If we use the instance id (assume UNC) to provide hints to the target zone, this means the instance id would need to change should the instance move locations. That's a no-no by everyone's measure. 

So, now I'm thinking more about Justin's comment about an external registry.

Perhaps a glance-like entry with metadata that can change?
