Check out [1], more specifically: "For many Red Hat end users, it’s unlikely that this flaw gets that far. IT organizations using Red Hat Enterprise Linux to underpin their Linux container and cloud-native deployments are likely protected, thanks to SELinux."
It does, but is it a first-class citizen as it is in RHEL and CentOS? Also OpenShift is finely tuned to run with SELinux. This is something you would have to do yourself on another platform with, say, Kubernetes and SELinux.
I was just saying that instead of all the hassle of going into production with self-supported, on-prem Kubernetes on top of some new-ish distro, the sane way seems to go with Red Hat's Kubernetes on top of a battle-tested distro with extra security features that is all supported.
If you want to run your prod workloads on self-supported Kubernetes with SELinux and similar features yourself, sure you could do that. Is that sane? I'll leave that as an exercise for the reader. What do I know, maybe it is.
