Symfony 4.4 Messenger - Alternative approach to different middleware for producer and consumer

messenger.yaml

framework:
    messenger:
        # ...

        # Read more to learn why there are two buses (TL;DR: different middleware on each side - producer and consumer)
        # https://github.com/symfony/symfony/issues/32436#issuecomment-530565499

        default_bus: command.bus
        buses:
            command.bus:
                default_middleware: false
                middleware:
                    - validation
                    - add_bus_name_stamp_middleware: ['command.consumer.bus']
                    - dispatch_after_current_bus
                    - failed_message_processing_middleware
                    - send_message
                    - handle_message

            command.consumer.bus:
                middleware:
                    - doctrine_ping_connection
                    # Will be available as of Symfony 4.4
                    # - doctrine_clear_entity_manager
                    - doctrine_transaction

Thanks for this!
