I did notice that the game gives you a warning that the eater is getting difficult to control when you feed it too quickly. Maybe this is a new feature though.

Yes I've seen those, but there's no warning before it reaches the final stage. A one turn or two turn warning would be nice so it could effectively be dropped further away from the provinces of its creator.
