::std::copyable is too strict for copy constructor because it requires both is_copy_constructible_v and ::std::is_copy_assignable_v. A class has copy constructor but disables copy assign operator may sounds weird but it DO troubles me. Therefore, if you agree with me, I'll handle other similar requires.
