ENABLE_STATS doesn't do anything

The README suggests ENABLE_STATS to have the app export metrics to OTLP. This environment variable doesn't seem to do anything, I was unable to find any mentions of it in the go code. Was this something that was intended to be implemented but never completed?

When enabling this kustomize module, most services will be patched with a configuration similar to the following:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: productcatalogservice
spec:
  template:
    spec:
      containers:
        - name: server
          env:
          - name: COLLECTOR_SERVICE_ADDR
            value: "opentelemetrycollector:4317"
          - name: ENABLE_STATS
            value: "1"
          - name: ENABLE_TRACING
            value: "1"

It does indeed look like these variables don't show up anywhere in the code, e.g.:

This is a year old, I don't think Google cares enough to fix it. Closing issue.
