This one is *great* even if you probably might never need it.
That having been said, I do come across some queries written by hot-shots who use hints in their queries…. and they often don’t maintain the queries when the table structure has changed making the hints counter-productive. How could they remember where they have used which hints and know which ones to fix? How will they find the time to do so? Being able to demonstrate that the hints are no longer correct without changing the source is a terrific way of avoiding the „you must have changed something else as well“ kind of reactions from certain types of people.
