Impact
Accessing the properties or calling the methods will trigger a PHP 
        E_ error.
Affected Installations
Third party code which accesses the properties directly or calls the methods.
Migration
In general, extensions should not instantiate and re-use controllers of the core. Existing usages should be rewritten to be free of calls like these.
