[address-policy-wg] IPv6 allocations for 6RD

"Nothing is so permanent as a temporary government program." -- Dr. Milton
Friedman

If we decide to hand out /24s to 6RD and we think that¹s not a waste of
address space (even though nobody has been able to give me an satisfactory
answer I¹m willing to throw in the towel) make that a permanent allocation,
not a temporary one. The pretense that people will actually hand back that
prefix is, let¹s say, not consistent with current experiences in IPv4. Once
it¹s out of the bag it¹s out of the bag, never to return.
