I think empty configs shouldn't mess up validation; maybe something we can fix in the TypeSpec?

They would have to support null on the properties that are optional. One of our users ran into that problem

Maybe the issue is only with null arrays being possible parsed as existing non-array values, failing the validation. We could try making optional strings explicitly also support a null or empty string value.

I tested locally; adding an optional array key without defining an error gives an incorrect type error. We could allow an empty string in the schemas, but that might break parsing in some cases. A valid alternative, however, would be declaring empty arrays and objects with key: {} and key: [].
