For some the trade off is worth it, but your right in that it should be an informed choice and not one made out of ignorance.

you should always use a 3-step torque process in the correct torque sequence on any bolt or nut to reduce the amount of strain by spreading the load evenly and progressively. this will prevent you from warping the spacer, rim, rotor, hub, and/or mounting surface, as well as avoiding damage to the wheel bearings and other components.
