Needing 2x their units to puppet them has been in the game for a long time. You probably would not notice it in many situations because you often have a much larger army than your enemy.
There are a few oddities with how the 2x is calculated. Units in the redeployment pool do not count. One guy had to send a few more divisions to Sweden from Germany to puppet it. But the 2x has been around for quite a while.
