I would vote that you do this.  if autri shows up as something else,
then someone will complain and we can re-evaluate at that point.  The
likelihood is that they will always have a reasonable class.

Generally, most chip mfgs preprogram the class and OEM vendors almost
never change it.  (In many designs, they "can't" -- its hardwired.)
