A fatter short area at the clamp is more about marketing than technology.
imo the buldge on cf bars was to prevent crush failures from overtorquing a clamp to prevent inherent bar slippage. thus increasing the surface area to clamp too, increasing static friction. nowadays its prolly evolved to combat associated nuances.
