My iPad lives on a stand most of the day. Videos, presentations, docs, whatever the work needs. That is fine until I want a capture of whatever is on the screen. Taking the tablet off the stand for a few seconds sounds trivial, but it breaks the layout, moves the camera angle if I am recording, and usually means I lose the exact frame I meant to keep. Apple already has a hardware shortcut for this. Power plus volume works. It also means lifting or reaching for the iPad, finding the buttons...
