The template specialization of std::hash for std::experimental::propagate_const<T> allows users to obtain hashes of objects of type std::experimental::propagate_const<T>.
For a given std::experimental::propagate_const<T> p, this specialization ensures that std::hash<std::experimental::propagate_const<T>>()(p) == std::hash<T>()(p.t_), where p.t_ is the pointer-like object wrapped by p.
