_LIBCPP_INLINE_VISIBILITY constexpr size_type size_bytes() const noexcept { return _Extent * sizeof(element_type); }
- _LIBCPP_INLINE_VISIBILITY constexpr bool empty() const noexcept { return _Extent == 0; }
+ [[nodiscard]] _LIBCPP_INLINE_VISIBILITY constexpr bool empty() const noexcept { return _Extent == 0; }

I just aligned the neighboring member functions. I don't feel strongly either way. Like Arthur said, I like to keep the diff as small as possible, but I hear your argument around making the code look nice.
In any case, CI passed earlier before the whitespace alignment (https://buildkite.com/llvm-project/libcxx-ci/builds/5884). I'll land this later tonight.
