Since working on the issue and seeing a local CI failure, there's a failing test in symfony:^8.0

See: https://github.com/symfony/symfony/blob/8.1/UPGRADE-8.0.md#console

Remove deprecated Symfony\Component\Console\Application::add() method in favor of Symfony\Component\Console\Application::addCommand()

The rest of the application is probably fine though.

Throwing to the test tests/Wrep/Daemonizable/Command/EndlessCommandRunloopTest.php:22 something like the below would work to keep the tests working.

- $application->add($command);
+ if (method_exists($application, 'add')) {
+ $application->add($command);
+ } elseif (method_exists($application, 'addCommand')) {
+ $application->addCommand($command);
+ } else {
+ thrownew \LogicException('check symfony docs since both are gone.');
+ }
