If four bolts were superfluous, they would not be part of the kit.
Your statement is not incorrect, but these aren’t ‘bolts’, they are fasteners, there to keep a panel on, not holding the wing together. It’s the kind of thing you write up and let maintenance fix at the next stop. Inspection panel fasteners wiggle loose. Not a big deal in small numbers. I have reported such on many aircraft and still flown.
