This idea is beneficial for use cases that occasionally require a lot of resources but usually only minimal resources.

In my case, I have a pod that requires a lot of resources (e.g., 32 CPU cores). However, this pod only runs once a week, so running a node with 32 CPU cores 24/7 is cost-inefficient.

So instead of having one node with 32 CPU cores, we would like to run a small instance for scalers like Keda and scale the larger instance from zero as needed.

This would be really helpful for us. Other cloud providers already support this, support for this would prevent us from switching to another provider.

I also don't understand why it is possible to create an additional node pool with zero nodes from the CLI, but not have it autoscale between zero and n nodes.
