Comment 11 for bug 119467

This should rougly follow the approach of ubuntu-desktop: applications which can be considered 'optional' for a KDE desktop and are likely to be replaced with an alternative by many users should become a Recommends. Those are still installed by default, but changing a single application won't break updates any more.

E. g. in Ubuntu we did this for evolution and firefox because many people prefer thunderbird and epiphany. We also did it for network-manager, since it breaks for many users, and they should be able to uninstall it without much fuss. Other good candidates are CJK fonts, documentation, etc.
