For all intents and purposes, that's private API. It's _p.h headers that
happen to be installed. You can't rely on them being there.

Start with X = 0 and change X for every BC-breaking release.
Remember that this library (the 2009 version of it) may need to be
installed in 5 years time if someone wants to run a 2009 application.
Or we can use libkdeuiexperimental.so.X, provided that X changes at every
BC change too. Besides general BC, it would also have to change whenever
we move the code from the experimental library to the permanent library.

That one I don't like. What happens in KDE 4.4 when the
knotificationareaitem is in kdeui, but we have something different in
How does one compile code that relies on the KDE 4.3 experimental?
1) build kdelibs 4.3
2) install libkdeuiexperimental.so.0
3) build kdelibs 4.4
4) install kdelibs 4.4 (which includes libkdeuiexperimental.so.1)
5) build application
If we do that, we'll have to have a permanent ban on packagers joining
Akademy. They'd kill us slowly otherwise.
