Again: A random drawing, no matter whose it is, does not have influence on the actual publication. Kishimoto drew Sarada with the Mangekyo Sharingan and Boruto with some Biju chakra shroud, but we're not adding those to their ability sections for the exact same reason.

But to perhaps get some clarification on this, I asked him on instagram about it.
