There are still unnecessary filelist entries in some packages that could be cleaned up.

kactivities5.spec:
%dir %{_kf5_includedir}/* /
%{_kf5_includedir}/* /
-%{_kf5_includedir}/*.h
+%{_kf5_includedir}/KActivities/

kbookmarks.spec:
%dir %{_kf5_includedir}/* /
%{_kf5_includedir}/* /
-%{_kf5_includedir}/*.h
+%{_kf5_includedir}/KBookmarks/

kcalendarcore.spec:
%{_kf5_includedir}/KCalendarCore/
%{_kf5_includedir}/kcalcore_version.h
-%{_kf5_includedir}/kcalendarcore_version.h
+%{_kf5_includedir}/KCalendarCore/kcalendarcore_version.h

Otherwise LGTM.
