Read again if you didn't get this.
I disagree. If the recipient does not check SPF, then it doesn't matter
what is in the SPF record. On the other hand, if the recipient *does* check
SPF, but fails to account for any old-style forwarders they have set up, then
their mail configuration is broken. This is not a reason to stop publishing
-all. There are thousands of ways to screw up your mail configuration that do
not involve SPF - and I've seen a good portion of them.
I would simply warn people that are *checking* SPF that if they use
forwarders, they need to check whether they are SPF compliant, and
configure for them (or stop using them) if not.
