This is actually a bug. If you install only @core, it should be 
pulling in fedora-release-nonproduct, not fedora-release-server. I 
think this is fallout from the change in depsolver from yum to DNF. 
(Yum would attempt to satisfy the dep with the shortest dependency 
chain; DNF uses a different algorithm).

Please file a BZ.
