json.hpp undefines JSON_STRICT_NUL_HANDLING and JSON_USE_LEGACY_DISCARDED_VALUE_COMPARISON at its end. Code that builds on the library after it, such as the planned json_view.hpp, reads them from detail::abi_config instead. The constants live in the ABI namespace, which already encodes both settings, so they always match the basic_json in use. Signed-off-by: Niels Lohmann <mail@nlohmann.me>
