It is reasonable to think that there the significant drawbacks associated with that hacked-together solution are no longer necessary because modern diets easily give adequate vitamin D.

So you're saying pale skin is a "hacked together" solution but modern vitamin supplements are not?

No, that's not what I'm saying.
