Glad to hear you're thinking about this. Understanding the complexity provides power, but the tradeoff in this instance doesn't feel quite right.
For example, etcd is a powerful primitive, and then more complex/sophisticated systems can be built on top of it.
I wonder if an 80/20 solution that is simpler than fleet/systemd for pushing work into a CoreOS cluster would be a win, and then more complex systems (e.g. Kubernetes-esque orchestraction) could live on top of that.
I took one look at Kubernetes, and decided that for our purposes writing our own orchestration scripts from scratch would be simpler... So many of these systems are hopelessly overcomplicated.
