Not doing some amount of reclamation, will leave us open to a different 
pattern of human behavior.  In this case if we leave sizable chunks of 
address space obviously unused, no matter how trivial in the over all 
scheme of things.  It will be an existence proof that we really don't know 
what we are talking about, or that we have an "IPv6 agenda".

I'm not sure what for the reclamation should take but it does need to 
happen, at least all the trivially easy stuff.
