smart pointer traits

I found myself having to write this the other day, to allow me to use any smart pointer or a bare pointer generically. Is it worth adding it to smart_ptr.hpp?

template <class T>
struct smart_pointer_traits
{
        typedef T smart_pointer_type;
        typedef typename smart_pointer_type::pointer_type pointer_type;
        typedef typename smart_pointer_type::reference_type reference_type;
        typedef typename smart_pointer_type::value_type value_type;		
};
        
template <class T>
struct smart_pointer_traits<T*>
{
        typedef T* smart_pointer_type;
        typedef T* pointer_type;
        typedef T& reference_type;
        typedef T value_type;				
};
