The reason I wanted to use QML plugin in the first place was that I  
want to use my existing quite complex QWidget in my QML application  
with QGraphicsProxyWidget. And based on the documentation and  
examples, the recommended way to use QWidget's in QML applications is  
to make them as QML plugins.

By including the plugin in Qt's resource system would make deploying  
the plugin with the application a bit easier.
