Currently, Swashbuckle automatically generates oneOf schema for types that have descendants. This is not the wanted behaviour in some endpoints like /states/current where StateDto is the response type but PastStateDto, its descendant, may never be returned.
An attribute and a Swashbuckle filter should be implemented that allow adjustment of the OpenAPI generator behaviour in situations like this.
