I think the # one thing neglected in small PSK is shelter. There is a definite trade off between size/weight and durability regarding shelter. 4 season tent vs space blanket.
This what I have come up with as a minimum.
20' of nylon cord for rigging
5' or so of duct tape folded flat for repair/reinforce
space blanket
.99 cent poncho
Vac packed to reduce size. It is not as big as it looks. The space blanket is on the other side and you cant see it.
ETA: bag it is vac packed in doubles as a water container.
