Labels missing from Namespace definition in 1.6.0

Elastic Orchestration Elastic Cloud on Kubernetes (ECK)
1

The Namespace definition in 1.5.0 is the following:

# Source: eck-operator/templates/operator-namespace.yaml
apiVersion: v1
kind: Namespace
metadata:
  name: elastic-system
  labels:
    name: elastic-system
    control-plane: elastic-operator
    app.kubernetes.io/version: "1.5.0"

In 1.6.0 it becomes as follows:

# Source: eck-operator/templates/operator-namespace.yaml
apiVersion: v1
kind: Namespace
metadata:
  name: elastic-system
  labels:
    name: elastic-system

Is the removal of those 2 labels intentional?

    control-plane: elastic-operator
    app.kubernetes.io/version: "1.5.0"

Yes this was an intentional change to remove an incompatibility with istio. See Istio sidecar is not injected into operator automatically · Issue #4395 · elastic/cloud-on-k8s · GitHub for context.

I had no problem injecting istio with 1.5.0. (I am in the process of upgrading to 1.6.0)

This (1.5.0) was my first installation (the version I started with) however (not an upgrade) fwiw.
