this other thinks that a reserved chunk of v4 space to carve out 
/28's and /30's for NATPT functionality is a compromise. A step in
the right direction.  presuming (facts not in evidence) that 
address return/reuse will occur (your favorite "market" proposal
goes here) - then we will see more and more interstitial gaps
that are not covered by a /22 minimum allocation size.

the -only- way to use them would be to then expand the "this is 
the reserved block for tiny spaces" to include those other
parts of the v4 space -outside- the reserved block.  

and yes, heirarchical routing takes an arrow to the neck.
