What I meant, though, is that a malicious server or proxy can do
*anything it wants* to the content passing through it.  Swapping
mimetypes is certainly possible, but so is changing all links to pdf
files that it detects to point to one on the attacker's site that says
"EFF ADOBE!!!".  (Or, you know, just strip the link out.)

When the attacker can do *literally anything* to the content, worrying
about it doing *one specific thing* to the content doesn't seem
