This change reduces test coverage. This PR demonstrates that the difference between C++ standards is not negligible, so I would prefer running the test for C++20 and pre-C++20 (whichever it was before, C++17?). Yet the added code is incorrect pre-C++20, so perhaps it worth it adding a separate test file to avoid complicating conditional compilation logic.
