Because no one has demonstrated that there is any utility to any
construction stronger than "we didn't sign anything".

So, uh, maybe this isn't obvious, but a) this is a chunk of what I
work on already -- threat modeling is a big part of that, and b) this
is the work of several lifetimes.  You have absolutely no idea how
hard what you're asking is.  But at this point, I'm exhausted by the
thought of even continuing to interact with a community this hostile
to the conception of user needs, so have fun, y'all.
