There's an argument to be made in general (which I don't think applies here - but playing devil's advocate) that says: When technology makes previous difficult things easy, this technology will be used to do more things that were previously impossible. I personally haven't seen anyone use k8s to achieve things that were impossible before. They just use it because 1) They think everyone is using it 2) They don't know how to do it any other way
