And so, to speed adoption of the SPF RR type, ISC is prompting admins to go back and look at their settings so that they can migrate. If a critical mass of admins publish SPF RR types, then the results of the experiment documented in rfc 6686 would be vastly different if repeated.  

SPF RR types are already standards track - see RFC 6652. An informational rfc warning that the standard is not being adopted should be seen as a call to fix the admins, not discard the standard.
