Yep, it really just works with key/value pairs, so config overrides happen to individual keys. The config system itself doesn't really have a concept of nested objects or arrays. The config provider that reads the json file takes the path, like JobSettings[0].JobName, and transforms it into into a key like JobSettings:0:JobName (IIRC).
I tend to avoid using arrays in config because of the unexpected behavior, and the risk of overriding something you didn't mean to. Anywhere you'd use an array you can usually use an object and bind it to a Dictionary<string, Whatever>, then ignore the keys.
