    Create duplex calls by overriding the new `RequestBody.isDuplex()` method to return true.
    This simple option dramatically changes the behavior of the request body and of the entire
    call.

    The `RequestBody.writeTo()` method may now retain a reference to the provided sink and
    hand it off to another thread to write to it after `writeTo` returns.
