One important distinction between gschem and pcb is that pcb has to deal with reality. It reflects real hardware, while gschem just displays a pure theoretical model. Theoretical models are always easier to deal with, because their whole purpose is easy handling of something.

In reality you suddenly meet hardware made of epoxy, glass fibers and copper. Hundreds of properties with trillions of possible combinations, if reality can be squeezed into a data model at all. That makes it much harder to develop such a data model and implementing all the actions.
