      Description

      Commands such as currentOp and ping are explicitly intended not to take any LockManager locks; however, they may end up acquiring LockManager locks as part of acquiring a MODE_IS lock on the oplog when afterClusterTime is specified in the readConcern object. I think it would be worth considering have the server reject these commands when an afterClusterTime is specified to preserve this intent.
