Smaller adults, for sure. I'm less than six feet tall and I can stand in front of my F250 and easily look down at the engine, and AFAIK it is one of the taller (if not the tallest) packages that Ford makes from the factory. That people modify their vehicles is without question, and the examples you gave look like they're all aftermarket lifts.
