+* [f63fd8101](https://github.com/api-platform/core/commit/f63fd8101f8211707806e013668f50dafab2865d) fix(symfony): define use_symfony_listeners (#6344)
+
+### Notes
+
+You can remove the `event_listeners_backward_compatibility_layer` flag and set `use_symfony_listeners` instead. The `use_symfony_listeners` should be `true` if you use controllers or if you rely on Symfony event listeners. Note that now flags like `read` can be forced to `true` if you want to call a Provider even on `POST` operations. These are the rules we set up on runtime if no value has been set: 
+
+```php
+if (null === $operation->canValidate()) {
+    $operation = $operation->withValidate(!$request->isMethodSafe() && !$request->isMethod('DELETE'));
+}
+
+if (null === $operation->canRead()) {
+    $operation = $operation->withRead($operation->getUriVariables() || $request->isMethodSafe());
+}
+
+if (null === $operation->canDeserialize()) {
+    $operation = $operation->withDeserialize(\in_array($operation->getMethod(), ['POST', 'PUT', 'PATCH'], true));
+}
+```
+
+Previously listeners did the checks before reading our flags and you could not force the values.
