Could you point to anyone, anywhere, who has ever said that the odd 
history of the SPF TXT record means that it is perfectly fine to do
something similar in the future?

On the other hand, please look at all of the stuff that people outside 
of the IETF do with apex TXT records, and try and say with a straight face 
that SPF as as much as 1% of the multiplexing problem.
