> Which products do you think are only “container orchestrators”? Even Docker Compose is designed to achieve a desired state from a declarative infrastructure definition.

The way how something describes the desired state (declaratively for example) has nothing to do with if it is a container orchestrator or not.

If you open the Kubernetes website, do you know what is the first thing you will see? "Production-Grade Container Orchestration". Even according to their own docs, Kubernetes is a container orchestrator.
