Ha ha. A foni story. Thank you, David. It occurs to me that this could be a clever and amusing way of avoiding the challenge of explaining the origins of tafoni, which is a question that seems far from resolved. In its way, rockpeckers could be as good an explanation as some of the others that have been published.
