The problem with this argument is that CSV lacks the early adopter

SPF doesn't prevent joe-jobs until people start using it to reject
email. It doesn't stop collateral spam from systems that don't do
SPF checks. SES acheives this without co-operation from anyone else.
Well, fundamentally it breaks (for a small subset!) that all mail must
be delivered
It's an astonishingly bad idea to compromise the reliability of email to
protect it from spam, especially since breaking it is unnecessary.
