Random musing...
We've all seen over time some people saying "I'd really like mechanically to play race X, but I don't like the fluff/appearance of them so I don't. With the compatible rules, just say that you're the child of a human and race X, choose to inherit all the visuals of the humans and all the mechanical benefits of race X. You can even explain why your alien race dwelling on the astral plane is thinking exactly like a human, despite being totally different, physiologically and culturally: it's inherited from the human parent.
Neat. No longer any need to pay lip service to the fluff to mitigate the optimization of race, background and class. It will also allow races that are mechanically interesting but whom are hated by some GMs (you can play a drow... but every peasant will throw stones at you) to play a galadriel-looking drow so your peasant can't even guess.
