json-schema generation, specifying :additionalProperties

[NoahTheDuke]

Hey friends,

I have this schema:

(def Item
  (m/schema
    [:map {:closed true}
     [:description [:maybe :string]]
     [:id :int]
     [:name :string]
     [:type :string]]))

Calling malli.json-schema/transform on it returns:

{:type "object",
 :properties
 {:description {:oneOf [{:type "string"} {:type "null"}]},
  :id {:type "integer"},
  :name {:type "string"},
  :type {:type "string"}},
 :required [:description :id :name :type]}

I would like it if {:closed true} would set :additionalProperties false, which would align it with the spec.

Thanks so much.
