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.
