Have you had a car made in the last 15 or so years? Nowadays ignition switches do everything but starting the ignition system. As the car is fully controlled by a computer, the key is an electronic gizmo that authenticates the driver as the owner and signals the starting sequence. The revolving movement is completely unnecessary and just provided for familiarity purposes, there are cars that instead of a key have a card and start by pushing a button. My bet is that maybe in 2005 GM was building the first switches under this principle, thus the need to preserve the electrical characteristics of the system, so the data transmision channels between the key and the computer wouldn't get compromised.
