Following the recent schism and the war that followed between Castriya, Salvadere and their religious allies, it seems more necessary than ever to introduce a more serious penalty to people who have a split religion, especially since these two religions hate each other's guts. Because, what happened in reality with Catholicism and Protestantism is that they've been killing, kidnapping and cutting each other until fairly recently.

So, whatever we decide to do, nations like Salvadere, the Lungarns and even my nation of the Glacies Commonwealth should not get out of this unscathed. We're all completely divided by religion, and none of us are putting anything into religious infrastructure. Not even Salvadere, and they founded a religion themselves!

So, TL;DR Countries which are completely split by religion should not shrug it of like it's nobodies problem. They've got to either solve the problem or face the consequences.
