the initial design of kde 4 says that kdebase-runtime is a required 
dependency beside kdelibs for running apps.
If you run amarok or digikam and opens the application related help this 
starts khelpcenter for displaying the help.
Because of that dependency khelpcenter is located into kdebase-runtime.

systemsettings is currently located in kdebase-workspace and will not be 
available when installing single applications.
This means that for any single application kdebase-workspace is a 
required dependency.

One additional item is to move systemsettings to kdebase-runtime as 
mentioned above.

if kdebase-runtime is still a required dependency for any application is 
there still a need for your request ?
