Yeah. Truth I believe is...bikes are a lot about looks when it comes to sales. Its the same thing with under handlebar tape routing. Shimano invented integrated shifter and brake levers. Campy invented under bar tape routing. Shimano copied it.
More about looks than saving a watt or two...but directionally correct.
