ACRP-MDP Subspecialty Designation- Is it worth it?

I just came across the ACRP website and one of their newer subspeciality certification.

The ACRP-MDP (ACRP Medical Device Professional) Subspecialty Designation is awarded to a clinical research professional who has demonstrated knowledge in medical device trials by passing a 60-question exam.

Is anyone considering getting this? What are the proposed advantages or benefits?
