No, the goal is for applications to develop their own KMessageHandler, I don't 
want to limit them.

As for KMessageBox and KPassivePopup message handler, I provide then for 
convience, so people doesn't need to reinvent the wheel. Also these could be 
assured that it respect the new KDE HIG and standards. 

I find this more easy for people, expectialy newcomers. You want your message 
to be passive popup ? then just use KPassivePopup message handler.

Then use KMessageBox directly.

Can be done.
