It is convenient to be able to change things like the ttl or the auto peering without having to bring down the interface. People might also want to tune from userspace the different mesh timeouts in response to changes in operating conditions (e.g. mesh density). But right now the only parameter that needs the mesh to be active is plink_action: one can only block or manually initiate peering after a beacon has been received from a suitable neighbor.
