I don’t think they should be required. The payload is actually a tuple, and element names are not required for tuples (and not even supported for single-element tuples). 

Your example is still possible without requiring labels; all that would change is that code which works today would suddenly break. Unless I’m mistaken, your proposal is about removing functionality and does not add anything.
