Given that you can only trust the last Received header, I'm not clear what
is accomplished.
False. You can trust the Received: chain back to the point where it reaches an
IP you don't trust to insert Received: fields reliably. Depending on the
circumstances that number can be anywhere from 0 to as many Received: fields as
there are in the message.
