Good features to have:

constexpr std::size (and also std::ssize)

template<class T>
inline constexpr std::is_simd_type_v = ...;

namespace std {
template<class T>
struct simd_element_type{
  using type = ...;
};

template<class T>
simd_element_type_t = typename simd_element_type<T>::type;
}

I belive the working paper is p2638r0
