The lobby service needs to retrieve the user's sequence ID before processing the message. Attaching the sequence ID to the event payload requires decoding the payload first, which currently happens on the worker. Moving this step outside the worker would slow down the Kafka message consumption rate.
By using headers, the lobby service can retrieve the user's sequence ID from the Kafka message without needing to decode the payload before sending it to the workers.
