Today's hotfix notes state that Family Members will no longer separate from the family and create new political parties.
Making Heirs unable to split from the family was a good and widely requested change. However, applying this to all family members seems like an overcorrection, as having less-favoured family members (like someone who wasn't selected as Heir) growing jealous and becoming political opponents gives space for an interesting thematic narrative.
Perhaps a middle ground could be looked at for next Hotfix?
Would like to read your opinions.
