Forbidden: uniqueItems cannot be set to true since the runtime complexity becomes quadratic

My Kubernetes CRD:

type FooSpec struct {
    // +kubebuilder:validation:UniqueItems=true
    MyItems []string `json:"myItems"`

Fails:

Forbidden: uniqueItems cannot be set to true since the runtime complexity becomes quadratic

This is documented: kubernetes.io validation docs

How can I ensure that the slice MyItems contains no duplicates without writing a webhook?

This works: listType=set

type FooSpec struct {
    // +listType=set
    MyItems []string `json:"myItems"`
