The standard wording sometimes uses add_const_t and add_volatile_t when plain const and volatile are sufficient. IIUC the difference is that add_*_t block template argument deduction like type_identity_t, but we never use add_*_t in such contexts.

Would it be better to use plain const and volatile?
