For backward compatibility, the existing structure where "v_noabi::array::* is defined in terms of v_noabi::document::*" is preserved as-is.

As far as I can tell, CXX-1830 can be resolved per its current description: there is no difference between the API for v_noabi::array::element and v_noabi::document::element (all public member functions are using-declared) and v1 removes the distinction completely with v1::element::view. Instead, CXX-1830 is repurposed to also track v_noabi::array::* API consistency as a whole with v_noabi::document::*.

Take advantage of (private) inheritance to defer implementation to v_noabi::document::element.
