Number delegation is now, and increasingly moving to range sizes that are not power of 10.

Where you still get PA assignments in the US in 1000 number blocks, a typical resell as likely  25 numbers or 5 as it is 100 or 10.   The latest moves in the US will force the PA to do small assignments also.

Unless the delegation size is a power of 10, it doesn't map into the delegation model of DNS with reverse-dotted zones.

You end up fully populating the tree down to the full e.164, and delegating multiples of 1 TN rather than being able to delegate a higher level part of the tree.

That is so unwieldy that you wouldn't do it - you get someone like Neustar to maintain the entire tree and provide a provisioning interface that handles an arbitrary sized delegation.  We could still delegate the NPAs out of +1 to the appropriate contractors on a per nation basis, but of course,  all of the nations that share +1 have to agree on a common +1 domain operator.  cc1enum anyone?  anyone?
