Its less about it having parity with the real world and more about fitting the setting. You're going into extremes to bring a point, and I understand exceptions are not out of the ordinary there is also a limitation of design relating to race. Like someone posted above, auri hairstyles have horns on them that add 'flavor' to them. Miqote ears limited certain hairstyles from looking as well as they do on other races.
We're outsiders, welcomed and accepted in the concept of 'hero' which is a carte blanche in its own right. We're the nameless, race-less, genderless hero and by design: an 'out of place' object. That's what it is, not what it can be.
I agree with more options to "express your character and its identity" but most of the suggestions here are going to an extreme that erodes distinction, rather than promote it.
