We agree that the goal is reliability (in this case, reliability and
security are highly correlated).  We disagree about how best to ensure

In particular, I take as a hard constraint what user agent
implementors are willing to implement.  We can debate for years how
many MIME types can dance on a the head of a pin, but it doesn't
matter if it's not implemented in the real world.  We can continue to
ignore the constraints faced by user agent implements, but that will
lead to this problem festering for another decade.
