Yes. I'm not sure why it would be removed. After all, the Window object  
has references to it.

That depends on whether the XMLHttpRequest object is used outside that  
Window. I suppose that with certain implementation techniques you can also  
limit the amount of resources needed. Rendering and such is no longer  
necessary for instance.
