Oh gosh, it leaves the edge exposed. Crazy.
I would not, under any circumstance, use that official case.
My experience; I walked with an iPad Pro in my hand and I went to an interview, so I was a bit nervous. I let the iPad slip out of my hand. It had the official Apple cover, which leaves the edge exposed. So it falls, and drops such that it dents the side. This in turn cracks the display. I learned that Apple will not replace a display when the frame is damaged.
