The C-stick is pretty much only preferred in cases where you need to make several quick/sudden moves like in Smash Brothers. It isn't very good for precise movement, as it wasn't designed with FPS games and the likes in mind. (Which is why it was never used to control the aiming in Metroid Prime.)
Making it the standard design would not make much sense.
