It's not a platonic argument, it's a practical one about high-speed
nets, perceived utility of AH, and expected market directions.

Platonic would be, "And do you not already have an algorithm that
hashes contiguous blocks of data?  And do you have a framework for
handling an extensible set of block-oriented algorithms?  And you
often process packets without care for the header value, other than
destination address?  Then, have you not already implemented the
spirit of auth-only ESP, and is it not implied by the code base you built,
although you thought you were coding to a different spec altogether?
Then is not auth-only ESP a done deal, roughly implemented in running
code, not merely a shadow thrown on the wall by yahoos in the internet
ether?"
