What is the likelihood of unevaluatedProperties being accepted as the json-schema for OAS 3.0? OAI/OpenAPI-Specification#1032 was accepted last month and does not include unevaluatedProperties.

@dskvr unevaluatedProperties is part of the next draft of JSON Schema, so #1032 couldn't make use of it yet.
