If it is possible to get exactly the same functionality without using
them, I guess we should.
The DNS community would do SPFBIS a favor if they try and understand
the current status of email authentication, and regard SPF as a set of
(missed) requirements rather than a means to trace a path that is not
paved yet.
If the next version of the SPF protocol (v=spf{>1}) will ever come
out, a better use of the DNS will be possible if the DNS will have met
those requirements by then. That does not depend on whether we insist
on an unworkable specification in the -bis of the current version.
