Great post and you make some very important points. I think the big problem is that this is most likely to be used in a criminal setting so a lot of those concerns will fall on deaf ears.

It is dangerous to simplify a diagnosis as serious as psychopathology down to a single checklist, especially when the ramifications of such a diagnosis can be so damaging.

Exactly but sadly it is indicative of the checkbox based approach to everything which has dumped experience and judgment in favour of standardisation (to the lowest common denominator). A lot of these sort of test are already just computer administered without even any human evaluation at all.
