That's wrong. Even if all servers in the world would check SPF you would

Why would I, as a SPF publishing domain owner, care if they have
anything else to check?
As long as they reject messages that fail SPF checks for my domain, my
problem is solved.
I guess I don't understand where the confusion is here. As Joar states, SPF
allows me to protect my domains from forgery and potential backscatter, because
anyone using SPF to validate senders can appropriately detect and handle SPF
failures for messages claiming to come from any of my domains that are forged.
It isn't even a forgery tool because if will return a false positive of
forwarded email.
