In some cases, the redundant connection can be considered beneficial. E.g. 
the multiple ground pins of a micro controller. Or the shield of a CAT6 
RJ45 connector.

How about this:
1) all internally connected pins receive the same pin number
2) the designer can attach an ignore flag in the layout tool to the rat.
 
This would make pcb ignore the respective rat when it assembles the 
currently unmet rats nests.
