Domain Keys sound like a bad/more complex implementation of the idea

Am I totally off base on this one?

Yes

No, "Dude" is right that DK is basically a more complex version of the

I'm not sure how the ability to say "yes this really came from us" is a poor idea. SPF is fundamentally broken if for no other reason than it breaks forwarding.
