They can't be curious about your character because that would mean taking into account all the interesting permutations that would entail.
perhaps having the opportunity to tell the game parts of our character’s story would set expectations about how the game responds to it that it would be impossible to meet. But until proved otherwise by experience, I’m going to continue to feel that it would still be better to be able to express it, even if the game couldn’t really do much with the information. And at the very least it might prompt more folk to think about who their custom character is and to roleplay that, rather than expecting the game to tell them and be disappointed when it doesn’t.
