:   This replaces the common alternative hack of editing the code to comment

We should just commit Jhn's wiring hints.

I know there are some objections to them that have been voiced here,
but they are clearly better than what we have now and don't break
anything.  Once we get experience with them, we can know the real need
for the advanced features that others have advocated for them.
