 In this case, since `object1` is a new object, there's no need to copy it
 into a blank object. What we needed was a deep copy, which is why we set
 the first parameter to `true`. If we didn't use deep copy, any default key
 that in the settings that referred to an object (such as the
 `multipart_params` key) would be copied by reference. Since there is only
 one default object, each instance would end up changing the defaults when
 trying to change the settings on the instance.
