Yes, I did.

My point is that the issue with a MUST level requirement is that  
because of what other specifications require (in the text/xml case,  
RFC3023) it is still impossible to satisfy HTTP's requirements,  
therefore user agents still do *not* (and will not) do what HTTP says.  
The four most popular browsers aren't going to change their behaviour  
regarding this. The only sensible thing to do, for the sake of  
interoperability, is to match what they do, which we still don't do.
