On the other hand, a lot of even the most basic tasks probably should be
done within a transaction.  But if the easiest way to do something is to
just run it outside of a transaction, I'm guessing a good portion of users
(including tutorial websites, people giving advice on forums, etc) will just
do it that way.  Mandating transactions forces users to be cognizant of
them.  Maybe that's a good thing...
