Yes, they could, but they would have no guarantee that Mozilla or any other
browser would either interpret that they way they want or implement the
behaviour they want in response, nor that a future version would not do
something slightly or markedly different.

Providing an rfc2557 MHTML mechanism would take care of the extreme case,
leaving room for a reasonable policy for "important stylesheet" that would
not necessarily mean "absolutely required" from this point forward.

Having said that, I absolutely would not advocate MHTML in the browser as the
*only* mechanism provided to authors to indicate how important or necessary
a stylesheet is, lest this feature get thought of by anyone as the only way
to go. I'd go so far as to say don't add the feature if nothing else is
provided as a fix for bug 17309.
