That's certainly a topic which could be addressed, but I don't plan on adding it to this patch since I don't have any specific idea in mind for how it would be discussed. However, the new "Program Output" section added by this patch seems a good place to add that discussion if someone wants to have a go at it as a separate patch atop this one.
