IMO it's because of this default in k8s storage class: https://kubernetes.io/docs/concepts/storage/storage-classes/.... Almost everything in a k8s cluster can be ephemeral... except your data! But they make the defaults insane and it eats a lot of people's lunches. It's honestly very sad. I fortunately haven't "lost" data in 25 years, but I still remember the pain when I made this kind of mistake.
