As written, the SCOTUS ruling seems to be against arbitrary, opinion based, or even poorly defined suitability, not the word itself. So I can see MA keeping suitability by claiming its well defined as a risk to public safety, right or wrong. What the ruling will do is lock down the reason and make it easier to appeal. No more "broad discretion", the old standard that the MA courts still apply despite the new language. Of course this may take a court challenge to get to this point.
