Kubeconform could be used as a validator plugin in [Kustomize](https://github.com/kubernetes-sigs/kustomize) (it's built into `kubectl` since v1.14) All needed is just support [KRM](https://github.com/kubernetes-sigs/kustomize/blob/master/cmd/config/docs/api-conventions/functions-spec.md) as input to Kubeconform. I will create a PR for you if the feature is accepted.
