I do have to say that with the difficulty in getting ISP & other admins
to buy into SPF, anything that keeps things easy is a good thing. The
DNS lookup can return multiple TXT records. There is a certain virtue
to single use tools- look at unix :-)
(Then again.. look at emacs!)

else
it would just be called spf and there would be no v= at all.
But what does it imply about future versions?
The least threatening philosophy (to potential adopters) for future
versions
is fixing flaws in serving the original purpose, but remaining narrowly
tailored to that original purpose.
Since there are (or should not be) any critical flaws in SPF1, a
release of
SPF2 should be regarded as a contingency rather than an objective. The
1 does
not imply future versions *will* exist, merely that they *may*.
If however it is the intention to expand the scope of SPF and that
adoption of
fixes is contingent on also adopting additional objectives, then we
end up
"doing a Microsoft" and forcing unwilling upgrades. I cannot support a
project with that intent.
Much of this comes down to naming. SPF2 (if it is required) should not
contain
a reputation system. However a reputation system should be developed
to work
in conjuction with SPF1, but it should have it's own name and it's own
record
type rather than 'squatting' on a SPF record.
