As I said few times, I don't see it as the same situation. With both Estates and Development it was that the feature could very well be just a part of the DLC. I imagine that when they were added there were no plans to develop these features further; people with Common Sense can Develop land, people with Cossacks have access to Estates. Then over time with new ideas came the thought to incorporate a new feature using these systems; boostable institutions and new estates. The decision is made that it will benefit future development, if it is a free feature and they are added.We already saw this happen with estates and development for exactly the same reasons
Then you have Government Reforms which clearly will need to be developed further. Every time there is a new government this has to be tackled. There is no way nobody thought it was a system worth having in the base game. It's not something that later turns out to be a good feature to introduce for everybody, it's immediately clear that's what it is.
We don't have a situation where a feature was supposed to be a DLC feature that later becomes free for better development of the game,
it's a feature that was supposed to be out of DLC that was thrown into a paid content.
They are "fixing a mistake", but a mistake that increased the value of a DLC. It's definitely worth calling it out, that it shouldn't be seen as a good thing.
