The default.aspx could be an affirmation of the backend being used so that when you see that elsewhere you know the server tech is MS, a sort of advertising/brand presence decision. I thought of that too, but that's sort of like Toyota advertising what sort of engine a car has by leaving the muffler off of all the showroom models. Gearheads can tell the engine by the cacophony in the showroom lot, but everyone else will get the impression that Toyota's cars are noisy.
