In the past only "wires" in the wire wrap sense are mostly used. In one of the
examples I have one source and multiple sinks and that works. During the
development of the LCD update I had connected a sink with a sink based on a
programming bug and it showed a short! So I expect it works with multiple source
and multiple sinks.

What is the benfit? What do you want to achieve with this bit?
