 ## State of the world
 
 Dagger 2 has been turned on for SystemUI and a early first pass has been taken
-for converting everything in Dependency.java to use Dagger. Since a lot of
-SystemUI depends on Dependency, stubs have been added to Dependency to proxy
-any gets through to the instances provided by dagger, this will allow migration

-equivalent dagger version is using @Singleton and only having one instance.

 ```

-SystemUI. ContextHolder is just a wrapper that provides a context.

-variants (like other form factors). DependencyBinder creates the mapping from
-interfaces to implementation classes. DependencyProvider provides or binds any
