Can kube-proxy update the destination IPs directly in the data plane proxies?

Hi, I'm learning Linkerd and wondering why we had the endpoint watcher implemented in the destination service.
I'm asking because kube-proxy watches the updates of Endpoint/EndpointSlice and updates the iptables of the pods. Can we directly leverage kube-proxy and just let kuber-proxy make sure the IPs in the data plane proxies are latest?
