They are. They also force the braking action through the center of the hub, forcing the energy through the spokes and ultimately the rim and tires. This is fine on a sturdy mountain bike, but not ideal on lightweight aluminum or carbon wheels. And ultimately, your stopping ability is limited by the tire on the road.
Yes, you can stop better and easier in rain / long descents on disc, but I think that's about it. Disks came from the downhill world of mountain biking, and for road racing applications it seems more of a solution looking for a problem than the other way around.
