      SERVER-49890 hoped to verify that pipelining the oplog into a graphLookup on the local.system.resharding.slimOplogForGraphLookup view used the oplog hack for efficient lookup. However, the (amateur) observation is that while the code is performant as expected, $graphLookup does not integrate with explain. The work done by $graphLookup is allegedly completely unreported.
