Conceptually it is still a terrible idea to have multiple consumers (By multiple consumers I mean things doing different actions on a message, not concurrent consumers doing the same action) on a single queue. Why overload a queue like that for 2 different actions when one can fan out on an action to 2 queues with SNS? Then your consumer does not have to determine if the message is for them or not. Visibility timeouts are for concurrency/errors by a single action. Yes you could hijack it and have 2 consumers act on one message and do different things but that is confusing and no benefit over just having 2 queues
