The biggest reason these features should never have been added in the first place: the more opportunities everyone has to notice and be reminded of everyone's differences, the longer those differences will remain divisive. So because people are discriminatory, we shouldn't be more inclusive at the risk of enabling those who...discriminate? The only reason these issues are divisive is because those who are insecure with their personal identity make them divisive. We shouldn't appease discriminators at the cost of letting people express their true identities. Also, you cannot "remotely capture" ethnicity and culture in a single color code, even yellow. Yellow is light and implies a lighter skin. It's inherently (no matter how you want to argue it) promoting or portraying human skin as light. I'm not sure where you get to your conclusion but it seems like, based on the adoption of skin tone variants, the only ones amplifying exclusivity are those that want things to stay exclusive.
