Your title is misleading

You mean you want the ironman-option back, where you
can't quit without saving.
While i never played that way because i was always afraid to get a corrupted save and lose a bunch of playtime,
i am as always +1 for options to let everyone play the game they way they like.
(It is really beyond me why so many things are lacking here that was in Warband and i read never anyone complaining about.
You would expect the quality state of an old game is the
least thing you can expect from the new one.)
