  // For example, if deployments can be modified via apps/v1 and apps/v1beta1, and a webhook registered a rule of
  // `apiGroups:["apps"], apiVersions:["v1"], resources: ["deployments"]` and `matchPolicy: Equivalent`,
  // an API request to apps/v1beta1 deployments would be converted and sent to the webhook
  // with `resource: {group:"apps", version:"v1", resource:"deployments"}` (matching the resource the webhook registered for),

This allows configuration without re-installing or restarting deployments.

If the change is to a Kubernetes field (such as modifying a Deployment attribute), it will likely need to be install-time configuration.
However, that doesn't necessarily mean a PR to add a value will be accepted.
