I think other functions depend on the ECM knowing whether you're in P/N or in gear...
Stall saver
Torque converter clutch
Throttle follower (how the IAC counts change in response to throttle input)
How the ECM regulates the idle speed (i.e. how it chases overspeed or underspeed conditions)
Probably some other stuff too that I"m not remembering...
