I disagree.
I don't know to what you disagree, but SPF is not an anti-spam tool. Full
stop.

You say that here but in your last message you said:
" If SPF was adapted 99% (and always strict with no allowance of
not-listed servers), then you could also do blacklisting based on this."
You can't have it both ways.
Which is another problem I have with SPF evangelists is that they say
(now) that isn't not for blocking spam. But yet people are encouraged to
use it to block spam. Everything else proposed here has to pass the
reality test. It has to actually work. But for SPF we are lowering the
bar for some reason. I don't see why SA has any SPF if it doesn't do
anything.
