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
