Hi Wayne, No, I have not reviewed the patch. I had some doubts about potential problems caused by invisible pins creating hidden connections. If user is neither aware of their presence when selecting a symbol, nor will notice them after they are placed on a schematic sheet then he may end up accidentally connecting them to some wires. IIRC we do not have an ERC test to check against such case, so I was not sure if it is a safe change.
