Are the new features really readable? I have no idea what this code from the OP is meant for:

    #[SkipDiscovery(static function (Container $container): bool {
        return ! $container->get(Application::class) instanceof ConsoleApplication;
    })]
    final class BlogPostEventHandlers
    { /* … */ }

As a side note, even PHP's official wiki cannot highlight correctly the multiline attributes behind a "#". See https://wiki.php.net/rfc/closures_in_const_expr
