And I really think that having different version numbers for different libs
with different features and different bugs are a good thing, otherwise you
have no chance to keep the various versions of the libs apart.

I think so too.
Every other lib increases its version number with increasing version.
Once somebody had a problem and KDE didn't start. Well, it wasn't easy to
find out which version of KDE was installed at all, since it might be helpful
to know whether e.g. 2.0.0 or 2.2.2 was installed on this box.
