With the caveat that I skimmed this thread and did not read everything, so I apologize if I'm repeating something that's already been discussed...
I think it's really cool when fantasy races reflect more diversity than the "white folks in makeup" sensibility. I have never played with anyone that had any issue with asian-looking dwarves being the predominant phenotype for a culture, or with an NPC or PC being randomly described as darker or lighter in skin appearance, from whatever race. I've seen it taken farther too, e.g. elves with greenish skin or humans who discriminate and stratify based on impossible (in our world) eye colors. It's all in good fun, and while I've definitely been on the sidelines for some online or social media angst when it comes to such topics, I've thankfully never seen it in person.
What I do give a little side-eye to is when every time a group or subculture gets introduced that have nonwhite features, they happen to wear the fantasy trope hat that happens to correspond to real world tropes of that race. So the asian looking dwarves happen to live on the steppes, raid and conquer their pastoral natives, are ruled by khans, etc. I don't find that sort of thing to be racist really, it's just sort of lazy in a way that makes me really wish the representation could have gone further.
