In Chrome (WebKit in general maybe?) there are already plenty of examples
of violating the convention "configurable: true means deletable". For
example, attempting to delete any of the hundreds DOM interfaces that are
present on the WindowProxy does nothing. Using defineProperty to overwrite
them works but as soon as you delete that newly defined version the
original definition comes back.
