Peter asks "what good are they"? Or, words to that effect. The person who most comes to mind that continually warned about destroying honey enzymes was none other than Roger Morse, former Professor of Apiculture at Cornell. In fact, I was once in the audience when a person asked Roger just the question that Peter is asking. Trouble is, I cannot remember his answer...except that he was convinced they were very valuable. Peter, with your excellent library, could you perhaps find Roger's view on the matter and report it to us?
