No, that actually didn't enter into consideration when I was looking at my narrow bill. That's a much larger question--whether or not you have exit control--and it would mean actually more bureaucracy at the airports and at exit points south from the country.
Currently, as you know, the governments use different methods of determining whether or not you are domiciled here or living here: whether you had a bank account, whether there was correspondence coming to you, what your mailing address was. All of these things are taken into account. Exit records will make it easier to determine those issues, but I think that's a much larger question.
