I got an idea about cheating in Suzerain

Why don't they add like a in game cheat thing. I beat the game normally a few times now and I kind of just want to mess around and do stuff that would cost to much to do in a normal game or see how good of a country I can built with a infinite amount of funds. They could allow it when you beat the game normally once and if you use a cheat achievements can be turned off for that game.
