> I can say with certainty that it's not likely, it unconditionally does. That's not to say address re-use isn't possible over a long enough time horizon, but that bookkeeeping is delegated to the CNI
You are 100% wrong then. The kube-ovn CNI enables static address assignment and "sticky" IPAM on both pods and kubevirt vms.

Heh, I knew I was going to get in trouble since the CNI could do whatever it likes, but felt safe due to Pods having mostly random identities. But at that second I had forgotten about StatefulSets, which I agree with your linked CNI's opinion would actually be a great candidate for static address assignment
Sorry for the lapse and I'll try to be more careful when using "unconditional" to describe pluggable software
All good and i'll cheers you on the composability of k8s for sure
