To me, it means that using an (unqualified) member function pointer exposes you to source incompatibilities. It seems that that is a more general problem than with just Qt. We should document/warn against that effect and how to protect yourself from it, but IMHO it should not stop us from improving the API, even if that means adding overloads.
