fwiw, MXR (and even LXR) uses some content negotiation, and it
generally "magically works". OTOH it's transparent, so you shouldn't
"see" it :).

But yes, I'd say that content negotiation is a failure. Another
failure in that area is Link: :).

The problem with content types i think stems more from:
1. images generally having random file extensions because users didn't
understand them
2. users who were publishing content in other formats not actually
having enough easy control over their hosting providers to specify the
content type, or knowing that it was necessary

Partially, both of these stem from the internet mantra: be strict in
what you send and graceful in what you receive.
However, only computers can be strict in what they send. So "be
ignorant of what you send" + "be graceful in what you receive" results
in "no one can trust what is sent".
