What is one reason that the catagorial model remained the official approach to personality disorder diagnosis as opposed to implementing the dimensional model?

I believe the answer is:  There are not adequate data to support the switch

In this context, dimensional model refers to personality disorders exist at different levels depending on its severity.
Since the method of measurement is relying on psychologist's personal perception, the data that taken from this model are often vary and inadequate to support the switch.
