Yes, the main role KAssistantDialog was to replace the lack in Qt,  now that 
there is QWizard in Qt, there is no more reason to have KAssistantDialog.

Anyway, the creation of KAssistantDialog has made discussions.

First, we decided to forget the name "Wizard" in KDE in favor of "Assistant".  
If the API still use the word "Wizard" it's certain that programmer will 
continue to use that in the UI
(Maybe doing a crazy check for that is the solution)

Second, one of the project of KAssistantDialog was to use the power of 
KPageDialog to display a step list on the left (like in [1]). This has not 
been implemented yet anyway.  But this is a cool concept.

Others ideas have been placed here:
 http://wiki.kde.org/tiki-index.php?page=kdelibs4+TODO%2FKAssistant for others 

But since none of theses idea have been implemented yet, i don't know if that 
count.

Probably what we could do is dropping KAssistantDialog now, and putting it 
back later (KDE 4.1 ?) when it will have all the features.  But i fear that 
if we do that, QWizard will never be replaced in all our applications.
