Why not:

Because if you publish an SPF2 record without a TXT record, those of us

publish
anything.
Just make it clear what it means to not publish the TXT or not publish
the SPF2. Then it is the publishers choice.
My real point was adding the 3rd line, not quibbling over whether TXT
should be a MAY or a SHOULD.
