CIF in SoCal also does not allow the old style skull cap and mask, and my 2017 catcher learned to accept his All Star hockey style mask. Some kids would try to make the switch to it at playoffs time, which is just idiotic to play the whole season with one piece of equipment and then change.
Eventually, every youth organization will enforce the rule, as like everything in today's society, there is just too much liability risk for the lawsuits filed by parents of catchers who got seriously injured in the exposed area of the old style masks. Lots of hockey players complained about having to wear helmets too but they adjusted. So too will catchers.
