Add "/readiness" endpoint
Having a distinct endpoint for readiness probes, signifying service readiness for traffic reception, would greatly enhance operational efficiency. In our scenario, this endpoint could invoke the readiness endpoints of both OPA and Entitlements services. This process ensures all Policy dependencies are ready, affirming Policy readiness.
