Let me give a "half full" view of this "half empty" glass. This =
experiment shows that not all UA to the right thing, but some actually =
do. If the "forwarded" scenario becomes important, user pressure and =
competition will drive more UA to improve their handling -- or more =
customers to switch to systems that handle such messages correctly. So =
there is some hope.
