Compositing is not used to make drawings but graphic content (image, exploded, video, ....) For me it's a mistake to want to do something else with it.
Like my classmates, it's a bit like driving a nail with a saw. ;)
At most, you can make "pretenses" of drawing. But nothing purely technical. Besides, I don't see how we can make projected views that will be updated. Maybe we can tinker with images of details.
@gt22: it's not just for comm, I have the majority of my customers who use it to explain assembly-disassembly procedures for their workshop or for after-sales catalogs.
