How hard it'd likely be depends on whether you'd want to just do it for
INSERT or actually fully handle VALUES. AFAICS values can be used as a
<query expression> which means as the body of table subqueries, on either
side of UNION/EXCEPT/INSERSECT and other such places in addition to its
usage in INSERT.
