Backwards compatibility is the reason why it isn't an error now.
-hackers is not really the right forum to find out whether anyone is
depending on that behavior. I'd suggest you shop the proposal around
on -general or -sql and see if you get any complaints. (I think there
are a couple other cursor-related warnings that really oughta be errors,
too; might as well finger them all while you are at it.)
