They work. :-)

It's not a new interface. It's the interface implemented by all 
(scriptable) browsers and called Window by all those browsers.

We don't get to pick the name -- the name is what browsers already 
implement and what the Web depends on.

As far as I can tell that would be wrong. The Window object is a DOM
