Kubernetes doesn't need a flipping package manager or charts. It needs to do one single job well: workload scheduling.

Kubernetes clusters shouldn't be bespoke and weird with behaviors that change based on what flavor of plugins you added. That is antithetical to the principal of the workloads you're trying to manage. You should be able to headshot the whole thing with ease.

Service discovery is just one of many things that should be a different layer.
