Behavior with respect to when an error is raised is inconsistent. In both cases there is a very lossy conversion, why is there an error in one case and not the other? Inconsistent. On the other hand if you add an error in the legacy case now that's a BC break. One might argue that it should always have given a notice, but it didn't, so it's a change, and a BC break.
