Well ... honestly?
Since i find sending all food to camp to be basicaly exploit ...
And since i find going for food every time i want to rest kinda anoying ...
I dont do either. 

I allways have single character that is mainly "food carrier" instead. 

(No i dont gather all food that is in the game, but i keep somehow "healthy" amount i presume would be fitting ... usualy i have around 60-70 units on me at all time. 

 Even tho i missjudged few times allready, but then i just make partial rest, focus on food a little more and go rest again once my resources are gone. 

 )
So it would make no difference for me.
