which is another statement i'd agree with that's different from
the one i challenged.

the policy under consideration amounts to:

    we're not going to get deployment in V6 without a swamp.
    but, let's try to give this swamp a boundary smaller than
    V4's swamp.  and, let's not give early adopters full sized
    blocks unless they qualify.  so, for now, let's do /48's.

to me this has all the earmarks of good policy.
