I agree with this. The idea of the lore is that the leads of each Zelda game are reincarnations of the bearers of Power, Wisdom and Courage. Technically this could manifest into anyone, but the games have stuck to specific character traits throughout the series. Which is essentially become the identity of the franchise. Making ethnic changes for the argument of diversity in an existing series, is the wrong way to do it. Introduce those characters in the series, or create entirely an entirely new one. It’s like hiring a black person in a company to meet your diversity quota.
