You want to signal early that a node is unable to do what is requested of it. Its the same with unbounded queues, you need to put in limits so that alarms are triggered much earlier. infinitely spinning up new things is generally bad. Unless you are responding to an external signal. Minimum deploy times again are useful. There is a financial cost (on the cloud, not on real tin) to short term instances. So you need to have them on as long as possible.
