Half the world uses only Jus Sanguinis. It has some benefit in terms of clarity and incentives. If you want to be generous and welcoming, that is fine, and could work perfectly well in that framework. All such liberal values would just need to happen through a legal naturalization process. Under Jus Soli, we encourage people to violate the law and create situations where some members of families are citizens and others aren't. Nationality in general is a pretty arbitrary concept, of course. But if we are going to have it, my programmer brain likes the idea of minimal ambiguity.
