> I personally believe deprecating the SPF RR is the wrong way to go, but I'm guessing that discussion has already been had.

Overloading the TXT record has always been a Really Bad Idea. I'm with
drc here. While the draft probably is formally proper, it advocates the
worng decision and I cannot support it.

OTOH, mixing up routing layer with application layer and gilding some
IP addresses in favour of others is another Really Bad Idea; I'd rather
throw the entire business of supposedly Good and Bad addresses out the
window and start looking at the in-band data instead; ie. DKIM or similar.

While removing SPF can be seen as in support of above, I'm pretty certain
that it in practice just will continue as usual, in TXT records. Better 
then that we get to keep TXT records for free-form data.
