Issue

Hello,

In this Docs link
I believe that the // remove additional properties comment is kind of unclear, meaning: when I read it I assumed that by default any additional properties would get removed automatically, which isn't the case.

Additional properties get removed only when their JSON Schema has additionalProperties: false, see this issue.

My suggestions is to simply change the comment to mention this small but important detail.

There's other places where removeAdditional is mentioned like here.
