I see a dissonance due to combining of multiple goals.  The implementors 
on this list want
to pare out weightless specifications that appear obvious to us, the 
architects want to provide
hints about purpose.

I see mm's point but I also respect ys's wish to make clear that a wide 
set of impractical
(yet common, naieve) wishes are out of bounds.  It is easy to imagine a 
unworkable standard
that mandates things like downstream compliance with labels if we aren't 
careful.

Maybe an "unworkable approaches" section would make sense and satisfy 
everyone.
