Describe the feature
It would be great if Knative could support EndpointSlices. This is a new Kubernetes resource that provides a scalable and extensible alternative to Endpoints. Although there may be more cases where this pattern is used, I've noticed that Knative manually creates Endpoints in some cases. With the EndpointSliceProxying feature gate enabled, kube-proxy will read exclusively from EndpointSlices, unfortunately disregarding any Endpoints without any corresponding EndpointSlices and effectively breaking parts of Knative. I've been the main developer for this feature in Kubernetes and I'm happy to answer any questions or help anyone that's interesting in adding support for this.
