In CK2 lacked a feature to reveal your bastard.
I think most of CK2 players have experienced that dalliance with random ruler wife will produce better heir thatn yours but random ruler thinks its theirs and you cant legitimaze him.
I think CK3 should have feature to reveal and legitamize bastards even then if no one yet knows about them and thinks it their child.
Also would nice to have plot to investigate any child legitamcy.
