I think it is an individual situation. We have several customers who, due to arthritis or other problems, use a pinky hole and it has allowed them to keep bowling with less pain.
Like any other thing, there will be some who like it, and some who do not. We all throw the ball differently, so if you suspect it may help, then try it on a ball. If it doesn't help, then plugging the pinky hole is an easy fix and you can try other things such as changing pitches, span, etc. to help your issue. Good luck.
