Your references to 'old-style' forwarding and 'forgery' will be a lot
more credible when RFC4822 comes out and indicates that forwarding sites
SHOULD NOT behave in the way they've always done by preserving the
reverse-path.

I consider that a prerequisite for any standardisation of SPF; to do it
in the other order is putting the cart before the horse.
