Correct. It might make sense to do so, if you could recover the costs of=20
the work involved. This is the reasoning behind the Specified Transfer
policy that was recently adopted; it allows (once we're at depletion) for
parties to free up address space and get compensated. It's goal is not to
provide a windfall for those holding unused space; in theory, those with
unused address space should be returning it already if they can easily do
so.

One of the other benefits of improved utilization for returned space
is less space which is "sitting idle" and available to be hijacked.
