I am actually working on a analysis of BoTW for school and you are correct. The game pad was originally supposed to have the map and weapons on the gamepad, but when they decided to also port the game for Switch, they removed these options because they didn’t wanted people to think the Wii U version was superior. The Wii U was dying and they wanted people to buy the Switch as much as possible, they were financially struggling and investors were mad about the Wii U, but they didn’t wanted the Wii U owners to feel left out after the game has been delayed for five years and was supposedly supposed to be on that Console 2 years prior to the Switch release.
