      This ticket aims to address a set of minor gaps of InitializePlacementHistoryCoordinator - in particular:

      • requests should be resolved into a no-op when there is no shard in the cluster
      • a post-commit NamespacePlacementChanged oplog entry should be generated on each shard to notify change stream readers
