Seems like a massive waste of time to me, like hours vs seconds kind of waste of time. With 3D CAD, if I have a top view of a part and want to add a side view, it's like 3 clicks to just... make it exist. All views are derived from the 3D part/assembly, there's no effort needed to make new views pop into existence.
Maybe I'm out of date on 2D CAD knowledge, but from what I remember you'd literally have to re-sketch the entire part for the new view. Because it's drawn in 2D, you can't just "flip it on its side" like you can a 3D part. And then you have to make sure you actually sketched the part correctly and didn't forget anything.
I see it as analogous to programming with toggle switches.
