…to show `HttpKernel::handle()` will catch throwables (Nyholm)This PR was merged into the 6.2 branch.Discussion----------[FrameworkBundle][HttpKernel] Add deprecation warning to show `HttpKernel::handle()` will catch throwables| Q             | A| ------------- | ---| Branch?       | 6.2| Bug fix?      | no| New feature?  | no| Deprecations? | yes| Tickets       |Fix#16205| License       | MIT| Doc PR        | symfony/symfony-docs#... <!-- required for new features -->I suggest that starting from Symfony 7.0 the `HttpKernel` will start to catch `\Throwable` and convert them to a `Response`.This was first asked in#16205, I face a similar issue with Runtime component and Bref..----------The reason I push for this change is to embrace the request/response workflow of the Kernel without trusting the custom error handler. In an environment where you serve multiple requests with the same PHP process (read: RoadRunner, Swoole, Bref) you would write something like:```php$kernel = new Kernel('prod', false);while (true) {  $request = /* create sf request from custom environment */  try {    $response = $kernel->handle(request);    return ResponseConverter::convert($response);  } catch (\Throwable $e) {    exit(1);  }}```(pseudo code of course. Here is a [real example](https://github.com/php-runtime/bref/blob/0.3.1/src/BrefRunner.php#L30-L43))The `exit(1)` means a hard crash. For Bref Runtime it would result in a 500 error from API-gateway. Since the `\Throwable` is caught, the Symfony error handler is not used. If we would not to catch the `\Throwable`, then the Symfony error handler would be used, but it would print a Response instead of returning it. (Printing a response will just add HTML on the CLI...)-----------Other PRs and issues related to this:-#45301-#26514-#22128-#36885-#25467I'm happy to let the `HttpKernel` to catch the `\Throwable` exception right now, but I thought this very conservative PR would have a higher change to get merged.Also note that we do not specify any behaviour on our [HttpKernelInterface](https://github.com/symfony/symfony/blob/v6.0.7/src/Symfony/Component/HttpKernel/HttpKernelInterface.php#L43)-------To remove the deprecation message you need to add this to your config:```yamlframework:    catch_all_throwables: true```Commits-------7977a15 Add deprecation warning to show HttpKernel::handle() will catch throwables
