> The point is that if I blindly break a larger functions by functionality, I still have to understand the deeper functionality. So, I can't just skip when I'm debugging or deeply reviewing/inspecting the code, or doing a rewrite or trying to understand it. That's exactly what a well abstracted function should let you do. It only comes difficult with global state, and unexpected side effects. You should break up functions by intent.
