The issue is that I doubt any UA will allow any random web page to force
the orientation without a user interaction, especially if the browser
isn't fullscreen. I'm not aware of a declarative way to go fullscreen
yet so it might make this feature not implemented by most UA.
But again, I will not fight to have it removed, I just doubt that we
(Mozilla) will implement that any time soon and likely never if the
context stays the same.

Florian, do you think we could add those to CSS Media Queries
orientation values?
