This is a compatibility polyfill for the extension. You should include this package as a dependency of your project to ensure that your codebase would still be functional in an environment where the extension is not installed. The polyfill will not be loaded if the extension is installed and enabled.
composer require php-ds/php-ds
You can also require that the extension be installed using
composer install composer test
Make sure that the ds extension is not enabled, as the polyfill will not be loaded if it is. The test output will indicate whether the extension is active.
