In my experience, the web is a lot more complicated than that. There
are many interesting corner cases here, including but not limited to
downloads initiated by other documents / windows (say,
http://lcamtuf.coredump.cx/fldl/).

With content sniffing, we have learned the hard way that
second-guessing the intent of the owner of a server in terms of the
way the content should be interpreted by the browser will almost
always bite back. I think we're making the same mistake here (and in
several other areas, too).
