It's something that has to happen in the next decade, not
tomorrow or this year.  For the foreseeable future we've
to support both ways as transparently as possible.

Ideas to invent new modifiers for this purpose strike me
as horrible.

At this point in time everybody supporting  / publishing
SPF can also support / publish TXT.  If he picks SPF only
for obscure reasons he deserves whatever happens.

E.g. a TXT policy trying to include a SPF-only policy is
broken.

Why?   There will almost certainly be cases of that as time gos
on, and they need to work.

It's broken because there's no way to know if the receiver is capable and
willing to check type 99.  If they don't, the result is a permerror.

They may work, but there is no guarantee.
