Not to mention the possibility of later on pluginizing certain styles to avoid loads of dynamic function resolving. These ideas are not feasible to implement in time for Qt 5.0, and for compatibility reasons cannot be done later if the style implementations remain in the public API.

Does this also mean that you will remove void 
QApplication::setStyle(QStyle* style)? This API seems useless if you 
can't create actual style instances any more because they are public. On 
the other hand, I think that that may cause issues for some applications...
