 `Parameters` field has a `scope` and `namespace` field that can be used to
 reference a namespace-specific resource for configuration of an Ingress class.
 `Scope` field defaults to `Cluster`, meaning, the default is cluster-scoped
 resource. Setting `Scope` to `Namespace` and setting the `Namespace` field
 will reference a parameters resource in a specific namespace:
 
+Namespace-scoped parameters avoid the need for a cluster-scoped CustomResourceDefinition
+for a parameters resource. This further avoids RBAC-related resources
+that would otherwise be required to grant permissions to cluster-scoped
+resources.
