It even inspired a WWII plane game to use deferred rendering, which optimizes for having many lights on an object. Even tho they for the most part had only one light source (the sun)...

Many lights is not the only advantage. There are some deferred decalling techniques that I could see be very useful to a flight simulator for terrain drawing, for example.
