It's no add-on, GTK+ does it itself all the time.  If we'd do it the way
I'm proposing but without enforcing the use of RefPtr<> we wouldn't even
loose backward compatibility.  It'd be dangerous (at it is now) and
allow bad style though.  (Yes, I really think that using delete in high
level C++ code is bad style.)

Yes, but I think we should make it simpler, not more complex.
