Every map projection has trade-offs. Back when I was in grade school, we actually learned about different ones and that the Mercator enlarged land as you moved away from the equator. Geography class actually taught geography rather than being yet more liberal indoctrination. The whole reason why this current map change is political is because it is being pushed by the globalist Progressives as some sort of anti-racism crusade righting past atrocities in the name of colonialism. The Mercator projection didn't become standard because of a bunch of racists, it provided the best trade-offs to project a globe on to a flat piece of paper.
This is political because no one was stopping anyone from using any map type they desire. This is all about making a big pronouncement of how great the the UN is in virtue signaling ending colonialism. It's a bunch of puffery and nothing more. There are so many useful things the UN could actually be doing, but they're more concerned about far Left idealism rather than solving actual problems.
