Nonetheless I think Maciej is right. WebIDL could discourage use of  
course. Though I guess you are saying we might not need them at all, ever.  
Does that work for document.all?

I asked how exactly IE envisions to remove support for them on this list.  
I.e. if it is behind a version switch. I've yet to hear back, but I think  
that if either IE or WebKit removes support for them we can do so too.

However that somewhat depends on whether IE keeps support behind a version  
switch because then sites might do the X-UA-Compatible trick and will  
still work in IE while not in Opera. That'd be annoying. (I'm not up in  
the details on which sites rely on this exactly unfortunately.)
