I mean one could argue that anything hosted on k8s should be reproducible anyway. I completely rebuild my k8s servers on a rolling two week cycle. The pain from that forces people to check in everything they need because if they don't it'll be gone very soon.

And still it's a bit of a battle to get people to test new versions of things, k8s included. "But it's working" is as much of a rallying cry as it ever was, "cloud" or no.
