Yep! Last I checked kubelet will just refuse to work if you try to give it swap from "underneath", too.
I work with data science tools that require 16G of RAM eac for hundreds of users, and Kubernetes was an appalling choice of platform for it. It has cost the org millions a year more than it needed to, given the actual usage profiles involved. Unsurprising that big contributors to k8s have been.. companies selling compute.
