Companies with tens of thousands of sites, each needing multiple subnets 
is not the norm for end user allocations. And again- would the 
administrative overhead of a new /40 netblock really outweigh the benefits 
to our routing tables? I'm asking not stating...

But ARIN has the power to give the community the tools it needs to force 
aggregation (if the community decides they want)- even if it isn't ARIN's 
own policy.

I understand limited deaggregation for TE purposes- but that doesn't mean 
you have to let people go nuts. 1 or two bits is one thing- 8 (or more) is 
another animal all together.

So because v4 is screwed up we should let v6 get just as bad?

The time to fix these sorts of issues is now- before it's really live, 
rather than later.
