Not really, Fire and sword got guns, bomb and many other good features in it and i think it's very cool, why doesn't it exist in Bannerlord? 8 years development and not some content exist in previous game?
Because they are different game, and different game need to change and improvement. As for the foods point etc i personally don't think it's an improvement and I don't think there will be Modder doing this just to make it's realistic and more tedious.
Generally what they want to improve from Warband is 1000 vs 1000 battle in 1 fight, so with that kind of armies size the food system became tedious.
