Nomad does all of these either natively ( rollbacks/rollouts) or via external tooling ( Vault, Consul, a load balancer). Unix philosophy and all that, and besides, Kubernetes doesn't do load balancing, and secret management is a joke.
By that logic, Kubernetes does nothing that is offloaded to operators, CRDs, CSI plugins, etc. The fact that you can extend it with extra features and it supports that is kinda doing something.
