One of them is that the `additionalProperties` key [allows only object values](https://github.com/swagger-api/swagger-codegen/issues/1318#issuecomment-146302879) (which mean schemas), not boolean `true` (which would be equivalent to an empty object) nor `false` (which is the default if the key is omitted).\r\n\r\nThis makes the Nakadi API in the current form unusable with Swagger Codegen (these are simply ignored).\r\n\r\n"}}
