I believe that it doesn't let you just plug in another Headset and use it with the official Oculus store - but it becomes pretty trivial for 3rd party 'hacks' like Revive to let you launch your Oculus games on an unsupported headset, rather than needing to go through a ton of trouble to circumvent the DRM.
