Know if a pin is connected or not

When writing patches I sometimes find that I want them to detect if particular pins are actually connected in their parent or not and change their behaviour accordingly.

It would be good if IOboxes being used as an input or output to a patch had an “is this pin connected” output.

i remember IOBox (Node) had once a pin “isConnected”.

i liked this feature very much.
