This read-create RowStatus is used to build or tear down an entry in the VSL connection table, where creating a row builds the actual VSL connection and removing it tears it down. An admin cares because this is the operational control point for provisioning or decommissioning a VSL link between two virtual switch chassis, not just a passive status field. For example, setting this to destroy on an entry actively removes that VSL connection between the chassis, so it should be used deliberately rather than experimentally.
