 //   all "visible" networks (physically connected networks like ethernet and
 //   cellular or in-range wifi networks). If the network is stored in a profile,
-//   FavoriteState.IsInProfile() will return true.

-//   corresponding FavoriteState with the same service_path() property.
+//   NetworkState.IsInProfile() will return true.
+// * "Visible" networks return true for NetworkState.visible().
 // * All networks saved to a profile will have a saved GUID that is persistent
 //   across sessions.
 // * Networks that are not saved to a profile will have a GUID assigned when
 //   the initial properties are received. The GUID will be consistent for
 //   the duration of a session, even if the network drops out and returns.
-// * Both FavoriteState and NetworkState store the GUID. It will always be the
-//   same for the same network (i.e. entries with the same service_path()).
