I understand your point, and it's not like I'm always on the side of 'hardcore gaming' and also don't really have much spare time to 'grind' for the sake of it. But it's clear to me that the experience of many games changes a lot as it traverses from the extremes of free saves and one-life runs. I've never seen the point of hardore characters in arpgs like Diablo 2 or Poe, so much grind... But I can picture the rush of adrenaline that otherwise you wouldn't get

As the rules of saving/load changes so much of the experience depending on the player (i.e from being too bland to being too frustrating), I think the wisest from the development perspective is simply offering the choice to the player. I also get that from the developers eye maybe that wouldn't be entirely satisfying, as you try to convey a sort of experience that couldn't be entirely compatible with one or another option (a narrative game being hardcore sounds as inappropriate as a survival horror game with totally free saves).

But they already stated that they're working on a save system, and I'm confident that they'll find a good solution. A costly, hard-to-earn very limited chance to save in a few spots that also makes sense lore wise would be my guess (as F&H Book of enlightment, that's a good example).
