After collecting and reviewing bits of information, this is going to be another product packed with toxic features.
CK2 was a failed game in the way it was supposed to be about personal power and these days, proponents of the american system, which constitute the bulk of players, are statist favouring institutionalized power.
In CK2, rulers (including the player) were supposed to rule out of personality when players, in their quest for power, were obsessed with building the institutions to support their dreams of massive conquest and subjugation.
It seems, though, that Paradox still wants to deliver a product about personal power and has including binding mechanics that could force players to play CK3 as intended.
This wont work, there is going to be a river of tears at launch, PX forum is going to be bombed with demands for change.
At the end of the day, PX will backpedal and try to dilute as much as possible the design.
