Yes, I do actually think that hothousing is necessary for a child of 11-13 to be "at home" in a collegiate setting-- particularly to be independent in that setting.
It is not necessarily the case that one may only hothouse academic skills. In fact, I tend to think that early college entrants probably are more frequently in need of other types of hothousing-- cultivating beyond-age-appropriate skills in any domain where they are not naturally occurring/developing so rapidly.
On the social front, the executive front, yes-- I'd say that the vast majority of even those PG children who are ready to manage college at early adolescence probably require hothousing.
I'm not suggesting that this is an inappropriate thing, however-- for some children it is the least-worst option.
But it does serve to make them adults in a functional sense when they are chronologically still children.
I see it as a last resort, honestly.
