Steering Wheel Controls

It seems to me that there was still one unused pin, on the 4 pin connector that passes the 2 cruise and the horn wires.

Have you actually buzzed the clockspring and verified that it does not pass that 4th pin?

If indeed it does pass that line, I am thinking perhaps steering wheel controls could utilize that line and share the ground side of the cc with a second wire coming out of the connector.

I have a nice new aftermarket HU on its way from China, and it specifially states it has a "Universal Steering Wheel Control Interface" ...whatever that might be

Anyway, I am sure I will be sorely tempted to do something in terms of wheel mounted control.

The clockspring has the connectors molded in. On my 09 2 pins were unused prior to me installing the OEM cruise stalk. On Crashy, who's an 08, the clock spring only has one extra pin (the other may have the wire inside of the clockspring, but it is not brought out to a pin on the molded connectors).

On an 09+, with the 2 extra pins, you can ground the cruise stalk to the frame of the steering wheel and gain back one pin. And like you mentioned, use that one pin as the feed for the steering wheel controls and use the steering wheel frame as its ground. Most resistive steering wheel controls use more that one wire, but typically most of the important functions are grouped together on the first wire.
