 // SystemTrayDelegate is intended for delegating tasks in the System Tray to the
 // application (e.g. Chrome). These tasks should be limited to application
 // (browser) specific tasks. For non application specific tasks, where possible,
-// components/, chromeos/, device/, etc., code should be used directly. If more
-// than one related method is being added, consider adding an additional
-// specific delegate (e.g. CastConfigDelegate).
+// components/, chromeos/, device/, etc., code should be used directly.
 //
-// These methods should all have trivial default implementations for platforms
-// that do not implement the method (e.g. return false or nullptr). This
-// eliminates the need to propagate default implementations across the various
-// implementations of this class. Consumers of this delegate should handle the
-// default return value (e.g. nullptr).
+// DEPRECATED: This class is being replaced with SystemTrayController and
+// SessionController to support mash/mustash. Add new code to those classes.
