I always thought that the "service saver" idea was based on a combination of the thins mentioned in this thread along with the fact that in the (later I believe) 50s Zenith chassis had the wiring connecting points mounted on those brown strips providing test points above chassis, which I'm sure many will agree would save a ton of time and trouble.
