You all sound ridiculous. There are some schools that are at or near the top on LI that bring kids up, there are some that don't. None of that proves whether moving a kid up helps the kids development or not. Will these kids who were moved up be the best players on Long Island this year, no, will they be the worst players on Long Island, no .Each situation is unique so the generalized statements are just silly. I have not seen any kid who was moved up to varsity at any program where I thought the kid was in way over their head, I am sure it happens but have not seen it.
