Wow... I have never thought of the process in the linguistic terms "additive" and "subtractive". That actually changes the mental model for me. I have always thought, in less abstract terms, about removing shapes (carving out) and optionally sticking external parts (bolting on) to get the desired product. The specific add and subtract "language" presents it in familiar, abstract, and, more importantly, composable model.
