Why does kdelibs4support/src/kio/kfilemetadatawidget still exist?




Hi!
Looking at lxr.kde.org it seems like dolphin is the only "real" client of KFileMetaDataWidget. Dolphin is not using it because of
#ifndef HAVE_BALOO
    m_metaDataWidget = new KFileMetaDataWidget(parent);
#else
    m_metaDataWidget = new Baloo::FileMetaDataWidget(parent);
#endif

(How is a clause like the one above called?)
So, what might be the reasons for KFileMetaDataWidget's existence in kdelibs4support?

Cheers,
Michael
