The root is the whole object. For example, setting default value for the pid selector namespaces need the namespace of root🤦♂️

What does this for? I think it is impossible for an external plugin to using unix domain socket: I imagine that the external plugin runs as one pod that you do not know which node will be scheduled on, if the pod of "external plugin" and the pod "controller-manager" run on different node, there is no way to use unix domain socket.

Yes. I plan to setup some "official plugin" like pod selector to use unix socket. They use the same SDK with others (but run in the same binary or container or pod with the controller).
The users can also add extra container and volume for the controller to deploy the selector plugin, for performance.

Implement service for every selector type?

Yes. The users should setup a service for it. Just like the webhook in Kubernetes. We need to setup a service for controller-manager, and create a WebhookConfiguration points to the service.
