Switched to flats about 8 years ago and it saved my riding. With clipless pedals I was pulling up with my legs too much at the bottom of my stroke, and it was using muscles in funny ways. Curiously they didn't appreciate that much, so my calves and quads were in constant pain. Switched to flats at the suggestion of a PT and the pain vanished. So it wouldn't be out of the realm of possibility to add "medical reasons" to your list.
