Indeed, the game isn't optimized for survival, but with a few mods you can come damm near close to it. At this moment I'm still in far harbor, and actualy its quite hard. Regarding your comments : 1) when you lower your timescale, you won't have to eat/drink every 10 minutes. 2) Loot overhaul and not building any water pumps, makes purified water more rare. 3) carry weight can be modded. With the bonus of my backpack I'm now maxed at 160lbs. Together with a combination of mods which increase the weight of weapons and ammunition, their isn't much room to fiddle with a missile launcher let alone a fat man. 4) With true storms you can ad the spawning of feral ghouls during rad storms, even at level 45 i'm still looking for shelter. 5) Besides mods, there are things you can roleplay. For me: I don't do drugs, no power armor, no map (only in settlements or distinctive landmarks), no crossair and I don't take perks which grant some magical power. But I hear you, I do miss the atmosphere of Stalker. Hopefully the next Beth game will be a lot darker/harder. (Sorry for my language, no native speaker)
