a good sanity check for me :)
I see SPF as the best IP based rfc2821 MAIL FROM / HELO identity system. The
value of the "others" lies in addressing rfc2822 and other identities (e.g.
PRA), and in providing cryptographic alternatives to IP based.
There is value in checking both an IP based and crypto based system for the
same identity - because the IP based is more efficient (for a well
designed sender policy), and the crypto based would be checked only
if the IP based passes.
