Sprint and MCI have a track record with InterNIC and they have shown that
they can efficiently use the next-smaller allocation size.

Anyone who shows that they will be an efficient suballocator will get larger
blocks as they fill up their initial smaller ones.  If IANA did as you suggest
and allocated huge blocks to everybody who can fib together a business plan,
there would not BE any unallocated address space by this time, yet the number
of reachable hosts would be lower than it is now.

A great deal of work went into the InterNIC's allocation policies.  Before you
offer to rewrite them, you should do some homework and find out how they got
to be the way they are now.
