"macOS" is unusable for me without three finger drag. But then I have to deal with deciding between two or three finger dragging. Why not make everything work either way? It seems like requiring the user to remember UI engineering details to make the UI work properly. ("This is a toolbar, so you should three-finger drag that, but that is a map, so you should two-finger drag to reposition that. But this other web-based map needs a three-finger and zooms from two finger dragging. Is that an Apple API implemented map?")
