I have seen those used as seats after the wheel well on a Scrambler. That was plus the typical fold and tumble seat. I agree on it being a little dangerous for the passengers. In fact, it might put their head at just the right height to constantly get clunked into the roll bar.
I think everyone has the typical tumble seat since it is the most practical solution for the vehicle...period.
If you look at the pictures closely, the added fold down seats are at about the same height as the top of the wheel wells in the jeep. That is a bit higher than the butt area of the OEM fold down rear seat.
I do agree that seats should never be mounted to the rear wheel wells.
CJ-8's built for export were available with longitudinally mounted folding seats that sat above the wheel wells. The CJ-8 wheel wells, however, are lower than the CJ-5/7 wheel wells, which means if you really wanted to put jump seats in the back of a 5/7, I suppose you could modify the tops of the wheel wells to be lower, there is clearance above the tires for some lowering of the tops of the wells. Doesn't seem worth the effort though.

I believe what you run into is that there isn't enough headroom for an average size adult and I also believe it's illegal for street use in the US. Not something you're likely to get stopped for, but a passenger getting injured or killed in one if you got into an accident would probably place all liability squarely on you if it were proven that they would've fared better in a proper forward facing seat.

I think running a back seat sideways would be a bit dangerous in a rollover depending on the height of your passenger. Just my opinion. The CJ-8 doesn't look too bad, but that TJ looks down right scary.
