I meant to find time to read Guenter's original email where he
initially objected to putting data into DT, and determine exactly what
was being objected to. I still haven't:-( However, the arguments that
Eduardo stated in his email do make sense to me; I agree that
temperature limits really are a description of HW. Details of which
cooling methods to invoke when certain temperature limits are reached
is also part of the HW/system design, and hence I would tend to agree
that they're appropriate to include in DT. Anyway, that's just my 2
cents on the matter:-)
