Not only when it is removed explicitly by the client. This is necessary to make sure the consumer record is removed from the management ETS tables (consumer_stats) and to avoid ghost consumers. For other protocols like AMQP 091, the consumer_status ETS table is cleaned up when a channel goes down, but there is no channel concept in the stream protocol. This is not consistent with other protocols or queue implementations (which emits the event only on explicit consumer cancellation) but is necessary to clean up stats correctly. References #13092
