That assumes you knew before hand to do that. The question is about the normal situation when you didn't. 

Also you totally disregarded the call site where there is no way to do a nice dict unpacking in python. The tuple case is super special and convenient but strictly worse than having properly named fields. 

To me this question sounds like it's about dict unpacking with one special case to keep backwards compatibility. This should be possible with a simple dict subclass in some cases...
