the entire outside of the kammback is almost definitely at a low pressure with [attached] flow at the speeds discussed. So the sides probably want to bow out as well as the top.
And concerning the fear of dangerous amounts of lift, I would think that unless the kammback is made from heavy guage metal, such amounts of lift would tear it off the car before it caused a huge control issue.
