Disregarding stealth mechanics being broken, they kinda are.

This is where a more classic inventory system should be introduced, instead of this nonsense of unlimited capacity on your person and carry weight.

If instead you have the old-style inventory system of slot placements - let us use the Resident Evil 2 remake as an example - you have a finite number of slots in which your carried items can be, it is up to you to play a minigame of tetris to carry as much as possible. Can be extended by wearing backpacks, pouches, and such.

Remove the 'send to camp' feature, replace with a 'bag of holding' feature introduced later on in the game.

Although I would not mind just removing the 'send to camp' feature and not bother with 'bag of holding' because it is stupid.
