IIRC I did this way so the inner struct was hidden and you just had to instantiate the upper struct with only the public fields (I explicitly did this way cause I didn't want another struct just for Major, Minor and you can always use the other struct without instantiating the private one). This is to say that unless something really needs it I think exporting this structure is meaningless

This is intentional. It'll stay not exported for now.
