Ah, I see what you mean. I wonder what kind of real-world issues crop up if you identify ∅ with no output along the output channel.
Another way to approach identifying W0 is with observational data collected by humans. Or (hopefully) with some stronger and more semantically-rich method that tries to separate the causes we really want to preserve from the causes that we regard as interference.

I generally think of ∅ as the “turn yourself off and do nothing” strategy.
