Because you then have to spread the data receiving code over all of the
programs. While it would probably be smaller than the authenticator code
itself, we still are faced with the same fundamental problem. If you want
to add a new authentication scheme that needs to receive different data,
you have to change every program. While the code footprint would be
smaller, the problem is still the same. :-(

Take care,
