Because (as far as I can see) Stefan proposed _adding_ a new
interpretation of one of the existing arguments, in a way that would
continue to allow the old usage.  The argument currently used for `mode'
would be extended to allow predicates as well, and the overlap between a
`predicate' and the existing allowable values for that argument is
small, and non-problematic in practice, I think.
