Password AutoFill "QuickType" suggestions in macOS Big Sur

I see the ASCredentialIdentityStore class is also available on macOS Big Sur. But it doesn't seem to be used anywhere.

Identities stored here on iOS appear on QuickType bar, on macOS I was kind of expecting them to appear has suggestions on the context menu for Password AutoFill.

Is this planned for inclusion on Big Sur, or should I just ignore this API?
