You are right about gschem and almost certainly pcb I do not think anybody is interested in using it for research. In pcb their are routing algorithms or other similar mathematical problems. What we arguing about is usually not real problems or any problems at all, usually it is the best method to implement something. Only real problems I could find is copper overlap and clearance. What pcb really lack is different clearance between different nets. Implementing stuff like selection of clearance and trace width from net attributes or similar should be straight forward although their may be a lot of arguing about best method to implement.
