Nope. That would result in separate copper pads that find.c thinks are 
magically connected but are not connected in reality (unless you soldered 
a component or wire on them that realizes the "internal connection").

These two things, invisible internal connection and "not shorted even if 
conected" are really different, sort of complementer features. Intconn is 
good for SMD 0 ohm resistor jumpers, the latter is good for the star 
topology.
