I think you are wrong. Every app needs to be selected, not only the 2 you mentioned.Luckily, you're wrong.
Only System Framework and Settings Storage need to be hooked. Better yet, the hooking is automatic with XPrivacyLua.
M66B mentioned that you need to select new apps to restrict them, because there is no api for it yet. So if what you said was true, than this wasn't needed.
