Another thing to keep in mind, since we're talking about security
policies in the first place, is that anything like this *MUST* be
"opt-in" on the part of the security policy, because what we're talking
about is circumventing an explicit security policy just based on a
user-provided binary saying, in effect, "don't worry, I know what I'm
doing."

Changing the meaning of an established explicit security policy is not
acceptable.
