RE: SPF v1 draft for review

I agree, at some point in the future:
MUST have RR
SHOULD NOT have TXT

Of course at that time, searching for TXT records SHOULD NOT occur.

This "point in the future" must be generous!  Maybe 1 year after the RR type
is assigned.  Maybe 2 years?  Long enough for the DNS servers and the user
interfaces to be upgraded to support the RR type!

I would play a little harder and say "SHOULD NOT have TXT"

This I think will give discretion to implementation authors whether to 
pay attention to TXT records or not - or avail such a configurable 
option in their software. A compromise if you will. The idea is to make 
people s/TXT/SPF/ in their zone files.

I would think that early adopters are more likely to make this change 
than those who implement after a RFC publishes the production protocol.

We have to draw a line somewhere. If TXT is allowed indefinitely, then 
we might as well not bother getting a SPF RR. But that also means we 
would be overloading TXT and imposing on it, which I am against.
