I think 'yes' is an easy answer. Having a convention that matches the is_same/is_same_v enable_if/enable_if_t paradigm could make some things easier, avoiding the need to wrap constexpr bool values in bool_constant<T> when there is no non-'_v' version of the check yet. But someone also has to write something that can be agreed upon, and then it needs to be enforced as well.
