This was my exact thought. But this technically isn't HBAC so much as "choose preauth mechs based upon the principal used to secure the FAST channel." It would also be somewhat useless if using anonymous pkinit to secure the FAST channel. Besides, long-term, we want FAST to go away. It is too cumbersome.
