When you're protecting reachability, what are you protecting? Whether or
not someone can reach something. I assume that the "something" you're
trying to protect reachability to would/must include things where you
enter your password.

Hence, I look at this entire problem a little differently than simply
trying to enforce a small subset of policies, or as a theoretical
exercise... If we can't prevent real world consequences with this work,
then --why are we doing it?
