As this class has nothing specific to Symfony, I suggest putting it in Twig itself |

This is related to the BC break reported in#21008 which has been introduced in#20093.
I think the BC break is acceptable since it is about bootstraping the form component with the twig bridge only, outside of the fullstack.
What I propose here is to ease upgrading by adding a simple runtime loader to the bridge, useful only when using the twig-bridge standalone.
So the upgrade would be as simple as:
use Symfony\Bridge\Twig\TwigRuntimeLoader;$twig = new Twig_Environment(...);$formEngine = new TwigRendererEngine(array('form_div_layout.html.twig'), $twig);- $twig->addExtension(new FormExtension(new TwigRenderer($formEngine, $csrfManager)));+ $twig->addExtension(new FormExtension());+ $twig->addRuntimeLoader(new TwigRuntimeLoader(array(TwigRenderer::class => new TwigRenderer($formEngine, $csrfManager)));Instead of having to write this runtime loader yourself. UPGRADE files and documentation should be updated accordingly (with or without this PR).
Please see#21008 for details and an exemple of how this could be applied.
