I think this comment would benefit a rewrite, to note what is actually still open. E.g.
```suggestion
   .. [#note-P0067] P0067: for integer types, ``std::(to|from)_chars`` has been available since version 7.0; for ``float`` and ``double``, ``std::to_chars`` since version 14.0 and ``std::from_chars`` since version 20.1. Support is complete except for ``long double``, which currently uses the implementation for ``double``.
