I don't know why the inclusions are wanted here... I think `<format>` should be unrelated to `<stack>` and `<queue>` when `_LIBCPP_STD_VER <= 20`. The inclusion of `<stack>` and `<queue>` was introduced in https://github.com/llvm/llvm-project/commit/04d4f4b3d4e4fd608a3bc3fe387006435f04b61d (https://reviews.llvm.org/D141290) which just implemented some parts of [P2286R8](https://wg21.link/p2286r8) (a C++23 paper).
