Which is what makes the entire discussion so entirely laughable.

I concur with Roy and Julian, leave Content-Type null with an undefined
content type.  while user agents persist in nonsense (such as decoding
UTF-7 when presented an explicit charset), this is out of our server-side
and authors' hands, and no spec is going to correct their misbehavior or
unsafe practices.

For some tiny minority who care, the very absence of Content-Type conveys
new, useful metadata that should not break 2616 definitions.
