It’s so stupid. They’re expecting an “Aha, we’re not deportale unde rthis new act because the baby wa sborn before it wa sput into effect!!” defence when the administration will just make up some other rule to include them anyway.

These defences only work when dealing with reasonable legislative process, not with people that write down the end result first and then write laws so that they lead to that end result regardless of the whys and hows.
