K8s with 1M nodes
How often do you have sudden host failures? Especially if you use a half-decent server with redundant components for the DB node?
Once in maybe 10 years?

The node failure rate is much higher than that. On a 1M node cluster of cloud-managed instances (AWS, GCP, Azure, etc.) you'd likely see failures a few times a month, if not more.

Yep. And the chances that the DB node with the control plane fails are therefore less than one in ten thousand.

It's not about failure, it's about servicing the host running etcd or the network around it.
