I think it does not solve that problem: you'd need the two internally 
connected pin of the switch to be drawn as overlapping pads so you 
wouldn't be able to pass a trace on that layer between the pads.

What solves it is the opposite: a way to explain pcb that two pads are 
connected even if they do not seem to be so, PCB-copper-wise. I have such 
a patch in my fork:

http://repo.hu/projects/pcb-rnd/intconn.html

you can have multiple groups of internal connections and find.c considers 
them as real connections.
