To an extent. K8s is a bit over-engineered in that regard. For example, it uses etcd to be resilient against the database failures for its control plane. Hardly anybody really needs this.

But it's not _all_ over-engineering, a lot of K8s complexity is justified once you get to a ~10-20 node cluster. Things like resource-based scheduling, gradual rollouts, and automatic rollbacks become important.

And just like with Linux itself, the set of features that are important to you, is often very different from the set of features that are important to me. So it's hard to create one definitive "standard" minimalistic set of features that would satisfy everyone.

etcd is not mandatory. On my home cluster I'm using k3s, with single PostgreSQL as a data store. Works perfectly on trash old laptops I've used as nodes.

Yes, but K3s is not K8s. And the design of K8s is severely affected by etcd limitations, even though all the large players have versions of K8s that use different storage backends.

K3s _is_ k8s – it passes conformance test suite and has CNCF's certificate. But I recognize this is a nitpicking not contributing to the discussion, so I'll yield here.
