"Records that begin with v=spf1 MUST be interpreted as

I am in favor of this.

I agree with the sentiment behind this suggestion.  It might
even be more useful if v=spf1 records were defined to mean

 spf2.0/pra,mailfrom,helo,pra

Could you clarify this, please? I mean, currently, pra is not part of v=spf1, right? I could see v=spf1 to mean this, though:

spf2.0/mailfrom,submitter,helo

I am not really sure, though, whether "helo" should be mentioned as a separate entity. It feels to me that "helo" is an implicit part of the mailfrom check (namely in the case of MAIL FROM: <>).

and if a sender is uncomfortable with those semantics then
they should publish proper spf2.0 records that override the
v1 entries.

As soon as this workgroup decides on its syntax, I will publish such new records. :)

Well, having said that, in reality I will probably wind up publishing both types of records, so as not to break downward compatibility.
