Let's also not forget, that many organizations went from multiple 
allocations to a single allocation. If we all filter anything longer 
than /32, we'll rearrange the flow of traffic that many over the years 
have altered through longer prefixes. Even I suspect I may occasionally 
have to let a /40 out now and then to alter it's traffic from the rest 
of the aggregate. Traffic comes to you as it wants to come to you. The 
only pseudo remedy that currently exists is to move some prefixes over 
to a different path. If you only have a /32, that'll be a bit hard.

This, more than anything, is what will effect this list and the people 
on it where IPv6 is concerned. Filtering longer than /33, 35, 40? Dare 
we go to /48 and treat them as the new /24? I know for myself, traffic 
manipulation can't begin until /40 (unless I split them further apart).
