Anyone using the value of this default directly must be prepared to
accept any of these forms. Direct use of the default is
discouraged; in most cases, NSBundle or CFBundle APIs should

I don't think this will help Jeff at all (other than to emphasise
that direct use of this default is discouraged), since NS/CFBundle is
what implements the default behaviour, and AFAIK neither of them have
routines to set the localization (as, indeed, you'd expect, since
it's very unusual for applications to need to do this kind of thing).
