Capabilities.cattle.io functionality

I noticed the following clause in Rancher’s documentation-

I assume from the CLI, these annotations go on the “clusters.v3.management.cattle.io” objects since that appears to be where our clusters are listed (when using Rancher’s own host RKE cluster via kubectl).

But what do they do?

The annotations are defined in Rancher’s code through these objects- rancher/cluster_types.go at release/v2.6 · rancher/rancher · GitHub

Is there any value to populating the capabilities.cattle.io/loadBalancerCapabilities and/or capabilities.cattle.io/ingressCapabilities annotation? Do any features become “active” in Rancher in response to this?
