So why not errata The Acts of Solomon?
We can and we may. But just because a card plays differently than originally intended (especially an old card) doesn't mean it needs to receive errata if it still functions well.
Personally I'd rather let players have fun with this, especially with States, Regionals and Nationals coming up in the next few months. If decks dominate because they can break this, or if it creates some strong NPE, then it'll probably receive errata. If it doesn't then it's just another fun interaction.
