I think about pcb as bunch of drawing primitives on different layers. Then there are structure so you could reference some of them at once then for example moving a footprint or a via.

Then you consider it good to tell which layers it should connect even to it physical end up on a board layer?

I also agree distinction between pin, pad and via could be removed.
