the genius behind designing additional control interfaces in a way that the original "remote-style" simply slides into it is the potential cost savings.
if the electronics, signal transmission pieces and power source are already supplied by hardware you own from the day of your original purchase... you're not reinventing (and re-purchasing) the wheel. the additional controller is just a dumb (and presumably inexpensive) shell. it's conceivable that new unique games could regularly be shipped with a customized control interface at little additional cost.

If you will not fight when your victory will be sure and not too costly, you may come to the moment when you will have to fight with all the odds against you and only a precarious chance for survival. There may even be a worse case. You may have to fight when there is no hope of victory, because it is better to perish than to live as slaves.
~ Winston Churchill
