I see the name was changed in order to preserve the old method as
deprecated, but since it can be removed in favor of the new method (no need to
deprecate internal-only APIs), the original name can be preserved with the new
behavior. Granted, the name isn't spectacularly clever, but it was very
convenient in that it was very descriptive.
