Now I understand your point.  Yes, under the old IPv6 policy, there was
no way a "decentralized entity" could do proper networking and aggregation.

This is why the new policy has so much focus on "be liberal in judging
address space requests", "HD ratio", and so on.

I hope it will work.

Of course.  And what makes this worse is that the "sub/national-LIR" level is
visible in external BGP, which is not the case for "normal" hierachical
allocations.

I would strongly favour this approach.

Of course I do not speek for the IPv6 WG or the NCC.

But I think the new policy is meant to be read that way, and "if we 
waste a /16 on all of the 10 (?) every supernational LIRs", so what 
(being provocative again).  Conservation is NOT a high-prio issue.
