The interesting thing is if the estate changes are completed before the war ends, that will open up a lot of new possibilities as you wouldn't need any knights in a realm at all potentially.
I don't know that I'd go *that* far. If you don't have knights, your region won't have much income. The new estate code will not be a return to the 2005/6 era, where you could control as many regions as you could defend.
