Not really. SPF makes the first guess of the naïve user correct, perhaps
-- but it's not really very hard to tell where a mail came from by
looking at the Received: headers, without SPF.
If it's an SPF pass, it saves you the trouble of looking up the IP
address in ARIN/RIPE/etc. That's all. AFAICT that's the only real
benefit we gain when the dust settles, after all the breakage which SPF
causes.
