That doesn't address the point -- the point is that these ISP's are forcing
the exchange of these blocks for new, previously unallocated space, and
leaving holes in the old 128/2 space.  These ISP's are massively
contributing to the depletion of immediately available address space. 

Why not adopt a reasonable policy to accept up to /20's or up to /19's in
the old B space so that organizations who already have these blocks can
use them?
