Now that you point it out, I'd imagine that aside from any bias pronoun choice would also be one of the least accurate suggestions offered. When somebody writes "my cousin is in town, do you want to meet", it's basically impossible to do better than a coinflip chance - and that's if offering a pronoun next was even correct.
