"culture shock" and other things of this kind are great for drama in an epic game, so everything that makes the character quite specific and possibly strange to others is something that will generate interesting interactions during the game. Anyway, D&D is an epic game, heroes are larger than life for all the good and bad reasons.
And sometimes it's good to break a trope just as some times it's fun to break it as well, so we are not forbidding anything, especially since the initial ASIs do not even constrain the final results of the character as he climbs through the levels, that's all. But we take every thing we can get to make members of a certain race truly belong to that race, and the racial ASIs (including the negative ones that existed in previous editions) helped with that as well.
We are not our characters, we roleplay them, and it's fun to play characters with strengths but also weaknesses. There was a campaign of Cyberpunk in which I was playing a very ugly street samurai, and it was really part of her personality, she was "that ugly yojimbo", but known for her ruthlessness and efficiency. Following a mission, she saved a vid star, who gave her tons of money and, because she was disturbed by the ugliness of her bodyguard, offered her surgery. So she became very beautiful in that age of affordable beauty. And I got tons of bonuses to social interactions. But the core of the character was no longer the same, so after i got more money, I went to the surgeon to reverse the changes, lost the bonuses and even more money, but at least I was "that ugly yojimbo" again.
