That is a problem I noticed on my last playthrough, when I found so many of them that I had to send more items to camp than I usually do.
However I would be even happier, if camp supplies could be used directly from the camp chest instead of having to have them in the characters' inventory. Since they are only needed for long rests, which are done exclusively in camp (so far), there is no reason a character couldn't just head over to the supply crate and get whatever ingredients they need to prepare dinner.
