These kinds of topo constraint criteria sound good. I also think that once you get some what-if outputs and your EE-trained-eyes see them, the remaining constraints would be on mixed groups that are not practical to separate, and so, those constraints would be circuitry selected by some polygon selection zone rather than being a topo definition. by that time, the autorouter has done almost all of its task anyway. You wouldn't want to leave nothing to the humans and encapsulate an entire BSEE degree in that program, "Would you?"
