I think the "label (edit: annotation) based configuration" has got to be my least favorite thing about the k8s ecosystem. They're super magic, completely undiscoverable outside the documentation, not typed, not validated (for mutually exclusive options), and rely on introspecting the cluster and so aren't part of the k8s solver.

AWS uses them for all of their integrations and they're never not annoying.

I think you mean annotations. Labels and annotations are different things. And btw. Annotations can be validated and can be typed. With validation webhooks.
