Describe the request

from @kittaakos:

I have noticed that the additionalProperties is absent from the schema. Hence, when generating types downstream, arbitrary properties are valid. Are they valid? In other words, is the "additionalProperties": false missing on purpose?

Describe the current behavior

If an extraneous property is present in the config file of the CLI it is not detected as "wrong".
