For that reason they don't want discs. Given the choice of 15lbs with disc or 14lbs without by people trying not to brake at all - the 14lbs bike will normally be preferred. There is a very large segment of the Road Cycling market that rides on dry paved roads where they rarely use brakes, and also want lightest they can get (for the money etc.) "racing" bike, whether they race or not. I think that will remain the largest segment.

Road Cycling is not by definition the most efficient or practical way to transport, or even has transport as the primary purpose. It is recreation, and that drive all kinds of products, colors, feelings. Making the argument that discs stop better is one few care about, and I have not seen anyone disagree with, just rim brakes are good enough for most Road Riding.
