If the change truly is generally purpose, it is generally preferred to have broader APIs. For example, instead of providing
direct access to each of the complex fields in [affinity](https://kubernetes.io/docs/concepts/scheduling-eviction/assign-pod-node/), just providing
a single `affinity` field that is passed through as-is to the Kubernetes resource.
This provides maximum flexibility with minimal API surface overhead.
