For one moment, let's think about all the two axis planes built today. Planes that are big enough to carry human beings (plural)
I would suggest that is as fatuous as asking how many aeroplanes built today for carrying human beings are wing warping biplanes that have the elevator at the front, have the pilot lying down on his face steering by levers and hip movement , and are catapulted into the air by a falling weight off of a rail and land on skids.
What the Wrights did with (albeit probably unintentionally) mimicking earlier established ( and indeed U.K. patented) concepts of flight control was but another step on the way, with two axis control and positive stability in the third, remaining acceptably applicable mechanisms for adequate control in flight at the time.
Direct control in roll is but a further refinement in controlled flight , it is not a definition.
