LGTM, I think in the future we should consider splitting providers by config data, and have components expose which config data they support. I think that would be both simpler from a user perspective, removes edge cases like this, and enables people to mix and match their desired configuration sources E.g.

--gameservers.k8s=gameservers
--filters.k8s=quilkin
// OR
--gameservers.file=gameservers.yaml
--filters.file=filters.yaml
