Very good, Selene.
I wanted this too, believe me. From the early days during which I discovered Oblivion, I wondered why all the food in the game is basically useless, so far as survival goes (and sleep is really only useful for leveling up and roleplay purposes). One of the first mods I installed in Skyrim was Frostfall, followed by a mod which makes food, drink, and sleep actually matter.
It just seems silly to me though, to expect that because Beth is remastering the game, that they'll add this one feature to it which has not traditionally been in ES games before, and which only a percentage of gamers would want or use. I mean, if you want to ask Beth to put this feature in TES6, I'm behind you all the way, because they'd be building that game from the ground up.
And then IF Beth did add some sort of survival mode, now the folks who wanted Spell Creation are pissed. "What about us?" .... The folks who wanted mismatched armor & clothing sets feel left out. It's better Beth stops at better graphics, which (I assume) are a relatively easy upgrade from them, meaning that they can now focus on wrapping up FO4 and moving on to whatever project is next.
