Yes. Why does the kcm look for a lib prefix now? Surely there's no good reason 
for that, the kde4 way was fine.

But we can still remove the prefix, can't we? You do so for oxygen :)

It should be true on fast local desktops, and false on slow/remote desktops, I 
suppose. IOW user configurable.

No, I think it's rather unrelated. The animations from the widgets themselves 
are (as can be found by grepping qtbase)
- opening trees in QTreeView
- moving tabs in QTabBar
- dockareas and toolbars

Does oxygen animate any of that?
I'd be surprised, since these were already animated in Qt4.
What's new is letting users turn it off, via kstyle using kconfig.
