The main work of the thing is as a cushioned environment for interacting with peers.
Schools (worldwide) utterly fail at this. (See: the bullying epidemic)
I think the whole idea of forcing certain groups of children to be together is a recipe for disaster. Some people simply cannot tolerate each other, and their mutual presence will spark conflict. Forcing these people to be together will lead to fights which make the school environment unsafe and distresses students. If a student is not respected by their peers, they must be allowed to find new peers. Otherwise, they will get bullied mercilessly.
