These syntaxes are required by the SQL spec. Furthermore, it's easy
to imagine far-more-probable cases in which the system wouldn't detect
that you'd made a mistake, eg
DELETE FROM tab WHERE key > 1
where you meant to type
DELETE FROM tab WHERE key > 10000000
I suggest counseling your client to learn how to use BEGIN/ROLLBACK.
This proposal strikes me as falling squarely within the rule about
"design a system that even a fool can use, and only a fool will want
to use it".
