Well I suppose it depends if you trying to assault an officer with it once your asked to get off the bike.

On a bike without baggage cases, you are likely to ride with a backpack?

Will a backpack provide additional protection? Or will it instead provide additional impact?

It is definitely better to have a backpack with you if you have no other place to stow things, IMO.

Could it increase your chance of a mishap?
Yes, if it is heavily loaded; such weight is much too high and probably will affect handling in the twisties. Any pack needs to be secured with a waist belt, in addition to shoulder straps. Another potential problem with a heavy back pack: Heaven forbid it, but if your bike runs into a hard object like another vehicle, you are more likely to be thrown forward into the handle pipe, and less likely to be able to jump high enough to fly safely over that handlebar if that happens. (So, as usual, you're limited in what you can take with you on your bike.)

If there is a mishap, a hard or sharp object in the bag could hurt you; spare riding apparel there could help protect you. (I've no experience with a "hard" back pack.)

And I've found that most liter size Pans, when warmed up, cook well.

..see hikers, skiers or mountain bikers as example, not strapped on tightly could it shift suddenly... alone the distraction due this... and the additional weight/mass will just increase the impact in a worst case scenario of hitting the deck... I also see especially the lower spine exposed to a higher risk... or when you tumble forward (like while T-boning a car), the thing will come up, literally smashing torso, neck/head/helmet against the object...
Yep occasionally I too carried backpacks on the bike, like the big pack (AKA locker on the back) during military reservists exercise... not to imagine going down with that...
I store even my Eastpack with notebook rather inside in the pannier, instead of having it on my back...

The thing to remember with a backpack is that if you have a rapid deceleration, probably due to an impact, the backpack will have inertia and will try to keep moving at the original speed through the soft bit in front - you. Then if you have survived the impact of the backpack onto your thoracic or worse cervical spine you may hit the ground back first when flipped over arching your back in a direction it was not intended to bend very far in over the back pack.

No, I will never wear a backpack unless it is a caterpillar protector with no mass, thanks.
