This is a todo reminder for some code cleanup.

In the chrome://md-settings we have controls and policy indicators that interface with prefs objects. In some cases a pref object is not readily available for use with the control or indicator, so a fake-pref is fabricated to glue the pieces together. Better ways to handle this would be to decompose the controls and indicators so that they can work with or without a pref object; Or, by creating pref objects for those systems/settings that don't currently operate on prefs objects
