There has been some big issues with what people have dubbed "North Korea Mode", making the game way too easy to play and removing the entire feudal point of the game. So we have made playing this way a lot less rewarding by reducing the amount of levies and income they actually get from doing this. It is of course still completely possible to play like this if you still want to, but you will be a bankrupt France with only 400 troops while the strong HRE will be raising a lot more troops than that. Small counts and dukes who go over their demense limit just a little bit will be a bit penalized but not to the same degree.

This change is a step in the right direction. But it only solves part of the problem.
Currently, "North Korea mode" works this way:
1. imprison all vassals
2. banish all vassals (takes all money and all titles)
3. conquer more lands; you'll have very little income but a huge army and a huge treasury.
4. as you acquire new vassals from conquest, go to step #1. you spend a lot on conquest, sure, but step #2 replenishes your treasury.
However, as Groogy said, it will no longer be practical to hold all the titles on your own. You'll no longer get a huge army from holding everything in your own demesne.
But that solution only addresses step #3. You won't have a huge army anymore, correct. But steps #1 and #2 will still be extremely useful.
With the current fix, NKM will start to work like this:
1. imprison all vassals
2. banish all vassals (takes all money and all titles)
3. auto-generate vassals, either via inviting stewards/holy men or by auto-generate directly on holdings.
4. return to demesne limit by handing out titles, meaning every vassal has 100 opinion of you from title grants
5. conquer more lands; you'll have good income and max levies because everyone loves you, a huge treasury from banishing the first generation of vassals, and easily enough money to hire mercenaries.
6. if desired, go to #1 whenever you want more money or whenever your heir takes power.
As you can see, the problem is not really holding everything in your demesne. The problem is banishment. It is simply too easy to imprison and banish everyone to farm a vast amount of money. And once you've banished all your original vassals, your new generation of vassals will not have any tyranny modifier. They won't remember that you just wiped out your previous vassals, because the new vassals did not exist when you did #1 and #2.
Please fix banishment, execution, auto-generation of vassals, and/or revoke title. These diplomatic options have barely been revisited since release and they have always been overpowered. Or do something about the tyranny modifier, making it a universal modifier, not a relational modifier. New courtiers/vassals need to know you were a tyrant, at the very least. Frankly, you probably shouldn't be able to auto-generate vast numbers of courtiers, either, but I don't know what that fix should be.
Simply put, Groogy, the fix you are describing does not fix the game. CK2 will still be mechanically broken in the proposed state.
