If you're running batch consumers, queue workers, or GPU inference pods that sit idle for long stretches, you can now let the HPA take a Deployment all the way down to zero replicas and bring it back up when demand returns — no cron job, no KEDA required for the basic case, no <code>kubectl scale</code> script in a Lambda.</p>
