yes, one _can_ but there are still things in KApplication that give some 
harmony across KDE apps like a consistent entry on the session bus 
(setApplicationName, setOrganizationName), the x11 start up id stuff, 
registration of KUrl as a metatype, checking writability of config, rtl 
awareness, some platform dependent stuff (e.g. the tray icon on a mac) ... 

i'm not expecting all of these things to magically go into Qt, but they do 
make KApplication, at least for gui apps, not quite optional without running 
into either inconsistencies or a lot of code dupe.

what it does mean, of course, is that our widgets and other libraries should 
never, ever use KApplication internally anymore as they have no need to 
(KComponentData ftw! :). only the actual executable applications should ever 
see / require this class.
