Yeah, I hate this. Speaking as someone who doesn't actually save-scum (I hate that term so much by the way) and only really goes back on a choice if I think back and don't feel that what I did matches what my character would likely do in that situation, this should absolutely NOT be the default. There are always modes in these games that limit you to one save file and have perma-death mechanics, they're gonna have one in this sooner or later. But it feels plain wrong to limit other player's experiences of the game in a way that doesn't ACTUALLY improve gameplay meaningfully.
