In the most part I agree, many people are making some pretty OCD claims, but this is a very strange design decision - to blow open the Italian-French border. If it's a difficult one to model with one province, why not simply add a province of mountains between the existing ones to represent both the fertile land and the defensible border? What we fear is that northern Italy will be easily absorbed by the big blue blob who no longer has to worry about the logistical or tactical difficulties of going over a mountain range.
