In video games, an exploit is the use of a bug or glitch, or use of elements of a game system in a manner not intended by the game's designers, in a way that gives a substantial unfair advantage to players using it.
Food have weight > sending food frees your carry weight > gives you advantage > sending food is an exploit.

Even if we were to take that definition as factual...
Which I would suggest keeping this part in mind :

There is nothing indicating that this goes against what the game's designers have intended.
I cannot claim to be a mind reader...can you?
As far as we know, this is on purpose. Ergo, according to this definition, not an exploit.

Obviously, it's absolutely ok to dislike this mechanic and suggest alternatives like you did (even just suggesting to remove it).

Although, personally, I'm fine with it and I also support OP's suggestion.
