This just looks like you're trying to avoid my question, which won't get 
us anywhere.  I'm not making a claim one way or the other, I just want 
to see some real world examples.

Sorry, arguing for a feature because it might be needed in theory isn't 
good enough.  It may turn out that the 101st case is so complex that it 
would never occur in reality, or it may not.  We don't know yet.  Let's 
try to keep this discussion based in reality and actually look at the 

Regardless of whether or not it's possible to cover 100% of all cases 
without the headers attribute, having the evidence will at least allow 
us to evaluate the effectiveness of any algorithm and help us come up 
with one that can handle as many cases as possible.

Yeah, I somewhat agree, but that's what the designer came up with.
