The problem is this. Let's say that I want to trigger a step in a "free trial" saga that sends an email to the customer 10 days after they sign up nudging them to get a paid account. If I can delay send this message for 10 days then it's easy.
However because SQS has a much shorter visibility timeout, I have to find a much more roundabout way of triggering that action.
But yes, a quirk.
