Well, the main argument for it in my mind is that we could avoid
breaking existing behavior in cases where it's not clearly essential
to do so. Perhaps that's less compelling than keeping the behavior
simple, since it's true that the specific cases we could preserve the old
behavior in are pretty infrequent. I'm not wedded to the idea, but
would like to hear a few other peoples' opinions.
