While in Italy a mother can give birth completely anonymously and give away the child immedeatly for adoption without any kind of registration (as in most other more or less civilized nation, I suppose) we have a constant stream of immigration, often abused women (forced prostitutes but not only) living outside the law in constant fear, who can't use that option or simply don't know about it.
Thus this option, the resurrection of the medieval foundling wheel... while it would obviously better eliminating the need for them ad interim it helps avoiding the trickle (very slight but unfortunately constant) of dead newborn found in public wastebaskets or wherever.
