(I'm a little confused by this, since my next sentence was explaining how
games can deal with this even if they don't spend the time to make it work

This is window.resizeTo all over again, and pages would use it for the same
reason: "our page looks best in 640x480" becomes "our page looks best in
portrait".  The results will be far worse: the user's device will be
flipping back and forth between orientations as he browses from page to
page.  Even if the user is simply tapping browser back a few times, the
button will move around between each press as each page in history picks
its preferred orientation.

Unless implementations deal with these issues somehow, this API looks
catastrophically broken.  It seems like somebody just took a native mobile
orientation API and translated it to JavaScript, without thinking about the
differences between task switching on mobile and navigating between web
