It is such a minor thing for power gamers who don't give a shit about races but is a neat change for players who want to change things up with different races. It won't bother AIs at all since it is just acting as if everyone is a human, and will mostly stop AIs who really like exploiting their laws.
Find a non-human being rude to a human and throwing empty threats, kill em. AIs can absolutely do that with asimov. I would rather have randomized lawsets rather than just 1 though.
