yeah, but there are plenty of cases where I intentionally don't connect 
to a pin.  For example, I might not use all of the IO lines on a 
microcontroller and I'll program the unused ones to be outputs.  On the 
board, they become a no connect.  On an op-amp which includes an offset 
null pin, I might not use it (not that I use them, but take the 741 for 
example).

I agree though that any use of a NA symbol must be done in a way which 
ensures no shorts in _any_ of the output netlists.  That would be very 
bad form.
