> Currently, {{NodeChildrenChanged}} events are sent to all persistent watchers unconditionally in client. This requires server to never deliver {{NodeChildrenChanged}} for node's descendants. It can not be true. So we need to filter {{NodeChildrenChanged}} for persistent recursive watchers.
> Splits from ZOOKEEPER-4466.
