Decoupling is good, but it can go farther...

As I hinted at (oh so long ago) during my presentation at the AMS  
workshop, one advantage of indirection-based approaches is that EIDs  
do not need to be allocated hierarchically, thus the existing policy  
constraints for address allocation no longer apply.  The RIRs could  
continue to hand out 'routing slot conservation policy'-constrained  
LOCs since they have the technical expertise to know what this means.   
They could also hand out the EIDs, but since the policy regime for EID  
allocation is fundamentally different than LOCs, it might make sense  
for other bodies (e.g., national allocation entities like NANPA in the  
+1 telephone region) to handle that task.

Of course, if EIDs aren't handed out hierarchically, the existing ACL  
models that rely on locator semantics would obviously break.  Some  
argue this wouldn't necessarily be a bad thing...
