I disagree..
Any sending domain that configured SPF and then became a spammer, would
find itself blacklisted pretty quickly.
The (admittedly minimal) cost of configuring a domain in the first place
should be a deterrant to spammers using valid SPF servers.
I think that's worth at least a small negative Spam Assassin value.

If you're NOT going to assign a negative Spam Assassin value for SPF
servers, then why SPF enable Spam Assassin at all?
