> what about when you don't need all that capacity anymore
It's not really an interesting use case... For the same reason that in every language I can think of, hashtables grow as you insert items but they don't shrink as you remove them, because if it got to size X once, it will probably do so again in the near future.
That said, decommissioning nodes will fall out naturally from our work on automatic load balancing for the 0.5 release.
