The context was supporting it in a layout tool and specifically how 
it impacts DRC and connectivity checking.  I'm just trying to 
understand the thought here.  If copper is left behind because of 
manufacturing, it doesn't really impact the layout process or 
connectivity checking.

It just struck me as odd that there would be support in a layout tool 
for no-net copper that might be connected to nets.
