Kubernetes does basically nothing to assist in integration or testing of services, and adds more complexity than the “VM complexity layer” ever had.

I don't think so. In the average company running VMs themselves, the person managing the VM is a different person that runs stuff on it. Even in < 5 people tech teams. And Enterprise-grade VM management software is completely out-of-scope for any dev person for that matter. Chances are I will never even know any details about the real hardware it runs on.

K8S is a different story, it can be managed by a devops team (or a really engaged dev ;)). VMs virtualize your network interface and can take care of some IP routing, K8S can route HTTP traffic and TLS-terminate it. It facilitates being aware of other services and multiple instances. Basically it's possible to get rid of nginx. And most importantly it runs the containerized applications basically on bare metal. Spinning up a test instance and destroying it 1 minute later is cheap, any dev can do it.
