      Resharding attempts to create an initial chunk distribution such that the collection will not be rebalanced by the balancer immediately after (absent of any topology changes, etc of course). It would be useful to collect metrics on whether the balancer rebalances a collection that has just been resharded in order to determine whether resharding's initial split policy is in fact creating a good initial distribution.
