It is no more a fail safe than the felt in the rep window, which limits the jack's travel (and also prevents a click). That limiting felt has a big impact on repetition speed and reliability. If you get a chance to watch the Kawai video, you'll see it pretty dramatically. When an action is played at high speeds and volumes, parts flex and compress beyond expected parameters.
