The military and the government have both verified this, but it's not merely a verification; it represents a compromise achieved among the various forces of the Kingdom on the list of enfeoffment.
Theoretically, the King has the power to overturn everything and start anew, but in reality, Caesar IV can only make minor adjustments.
He could remove a few that he disliked or add some barely qualified confidants without issue, but any more than that would cause trouble.
In fact, Caesar IV has done an excellent job with the enfeoffment of the nobles. Other than occasionally adjusting the location of fiefs, he hardly interferes.
Inserting confidants is even more out of the question!
The front is not the rear; without some ability to fight, one would only contribute to the enemy's achievements.
Even if he were to favor his confidants, it would be on the merit of their battlefield achievements, proving their abilities, before Caesar IV would dare to use them heavily.
