Since symfony/messenger 6.2: Implementing "Symfony\Component\Messenger\Handler\MessageSubscriberInterface" is deprecated, use the "Symfony\Component\Messenger\Attribute\AsMessageHandler" attribute instead.
The "Dvsn\SetConfigurator\ScheduledTask\TaskHandler\CleanupTaskHandler" class extends "Shopware\Core\Framework\MessageQueue\ScheduledTask\ScheduledTaskHandler" that is deprecated tag:v6.6.0 - reason:class-hierarchy-change - Won't implement MessageSubscriberInterface anymore, tag all ScheduledTaskHandlers with #[AsMessageHandler] instead.
Method "Symfony\Component\EventDispatcher\EventSubscriberInterface::getSubscribedEvents()" might add "array" as a native return type declaration in the future. Do the same in implementation "Bc\BrandCrockVariantProductPriceRange\Storefront\Page\Product\Subscriber\ProductPageLoadedSubscriber" now to avoid errors or add an explicit @return annotation to suppress this message.
