Rapid iteration at the component level would obviously require custom components, and maybe vertical integration, which clearly conflicts with point #1 about riding existing supply chains. But you can still iterate parts of the design that you more or less "have" to customize, such as the body material, axis geometries, and dozens of other factors I can't think of off the top of my head. The collected data can both be used to improve training and as input into the design iterations.
