I have used a portion of that capabilities for live debugging on prod machines to test things out before putting it through source code and using the regular CI/CD for deployment. However, the CD deployment does not rely on hot reloading because it hasn't been necessary.
On Kubernetes, running with regular pods it was not desirable. Maybe if we were deploying with StatefulStates.
