So for future KDE apps there is no "guideline" to use QML if possible
(option #2).. It's all still (and remains) what the app developer want
to do?

@nuno for kde components. I've experimented with the GIT components on
windows and they look very native and good. They should look equally
native on KDE and Mac. I'm just hoping they fix some bugs and make it
part of Qt 4.8 or 5.0. Since this stuff is making the app distribution
somewhat tricky as the components need to be installed manually.
