Should "diff_drive_controller" be listed in ros_control Wiki? [Question]

Currently, the [diff_drive_controller](http://wiki.ros.org/diff_drive_controller?distro=noetic) is not listed in the Controller List of [ros_control](http://wiki.ros.org/action/login/ros_control#Controllers) Wiki. Is this on purpose, or should I expand the list and add the corresponding link to the diff_drive_controller?
