Maybe.... Let's assume it foes for now.

So per this draft, it is in fact not possible to send <video> over 
HTTP/0.9, or ftp, or in fact any protocol that doesn't provide an 
explicit MIME type....

Thinking about this more, having the rule be "no sniffing" in this case 
might not be too bad.  Yes, if an Apache server is not configured in any 
way for your video it'll get sent with no type at all and not show up as 
video... but it also won't show up as text (which is where we are now). 
  And it'll be pretty obvious to you that it's not working and that you 
should get your server fixed, especially if web browsers provide nice 
informative error messages here.

That all assumes that people actually stick to not sniffing, of course.
