A lot changes between 1k and 6k rpms. Theres additional boost and fuel from the turbocharger just to give one example. So I think the argument is that the components can be broken in not strengthened through a gradual increase in the load.
If an idling car is working the same as a moving car, there would be no need for the break in procedure using distance as a unit of measurement. We could just leave our cars idling for xx hours and call it a day.
