Hmmm... I think this really only worked by accident and wasn't
explicitly supported by Emacs-24's doc.  And adding support for such
degenerate methods might not be straightforward in eieio-compat.el, so
I'm wondering where you've seen such use, to see how important it is to
provide that level of backward compatibility.
