Dumb question time, based on two questionable assumptions.

IF   one is the opinion TXT records should not be used for this
AND  one is of the opinion "fixing" (breaking? :-) ) wildcards to do this
    is not desirable
THEN you are left with a new RR type as the only solution anyway.

So, if those assumptions hold true, why would you want to invent two-stage
queries, when you can just do

$ORIGIN example.com
foo	IN	TXT2	"SPFv71"	"Here's my SPF String"
foo	IN	TXT2	"killspam3"	"Here's my other string"


IE encapsulate the type in the record itself, but not as part of
the freeform text field.

Sure you can't query by it (today) by type, but you can get all the
information back anyway, and if we wanted at some stage to query
by 4-tuple rather than 3-tuple, it would be obvious how to do it.
