      Description

      Under certain conditions, it is preferred to have a node start and join the replica set, but not be the target for any client reads.

      A config option to set maintenance mode on start would ensure that the member doesn't take any queries until an operator affirmatively verifies it's good to go. For larger deployments with lots of shards & replicas, a few nodes in maintenance mode waiting for manual verification is operationally safer than serving stale data.
