This can be enabled by decorating the base class of a type hierarchy with the new JsonDerivedTypeAttribute. Although no class is its own base, std::is_base_of::value is true because the intent of the trait is to model the "is-a" relationship, and T is a T. Despite that, std::is_base_of::value is false because only classes participate in the relationship that this trait models.
