Ya think? Where’s Captain Obvious when he’s needed.
In my opinion, the greatest risk would be older boys preying on younger ones, if actively homosexual youth are allowed. People are thinking about adults with children, but the fact that the boys are all officially “minors” don’t make sexual abuse not abuse. (And it doesn’t when it’s heterosexual, either!!!)
The level of supervision, and of grotesquely graphic safety instruction, would have to be greatly increased.
