That is inaccurate. If you increase your pad's contact with the rotor, you will increase stopping power. It's simple physics. More friction=better stopping.
Any reduction in contact area because of drilled and sloted rotors would be trivial. Besides, when you swap out your rotors you'll probably be upgrading to a pad with a better compound anyway, so any minimal loss would be offset by the pad.
