Torque is never a waste of time on a rotating, hard to get to component. Locks are good for close-fitting holes where the force of the bolt can mash the hole smaller as its nearing its prescribed torque. Lock washers also permit closer torque targets as they are made of spring steel and promote a sliding force, rather than the bolt head sinking into the attached piece. Seldom do I ever see a lock washer actually lock a bolt, unless the bolt is soft enough and the edges of the washer are sharp enough, but it does happen... use of lock washers also makes the socket stay on the fasteners better, due to the thickness of the washer being nearly the same as the chamfer on the socket; promotes full socket/fastener contact when you are in awkward position or cannot actually see the bolt.
