It is however the kind of thing that Tab wants to do for CSS (have a 
window.CSS object that is like a namespace object for some CSS 
interfaces -- the concept for which used to exist in Web IDL a while 
ago, but which I removed due to disuse).  So it might well make sense to 
add something to Web IDL to handle this again.
