It would be problematic in some dimensions, but it seems that perhaps
allowing them to return space in exchange for a larger block is part of
the problem, and maybe part of the answer would be to make them retain
the block and only allocate an additional block.  Route table growth and
all that, of course.  An alternative could be to delegate them a larger
"contaminated" block and allow them to incur the expense of cleaning it

* And I say that kind of tongue-in-cheek, since I don't really believe it
  to be easy to clean up a block once it is contaminated, due to the sheer
  number of local blocks, etc., which may exist.

With 24 million small businesses in the US alone, that's way too many apples.
