  * User-written controllers that reuse names of pod objects should evaluate this change.
  * When deleting an object with `kubectl delete ... --grace-period=0`, the client will
    begin a graceful deletion and wait until the resource is fully deleted.  To force
    deletion immediately, use the `--force` flag. This prevents users from accidentally
    allowing two Stateful Set pods to share the same persistent volume which could lead to data
