This seems like a UI issue, so I haven't changed the spec (it doesn't 
really talk about the location bar -- indeed it doesn't even require that 
one be visible at all). However, should anyone want to discuss this 
further, e.g. to organise browser vendor plans, you are welcome to do so.

Well, the requirement (search for "override URL" to see what we're talking 
about here) isn't on the location bar per se -- it's just on what "the 
document's address" is, which is used in some of the APIs. You don't have 
to show that, indeed you could show both, or something else, or nothing.
