Could be my technique. I have only built on plane. But after talking to several show winners about the riveting technique, I found them using the back riveting technique when ever possible. And I found their rivets to be superior. I was sold and have converted to this technique when ever possible.
Curious about the physics you refer to as supporting conventional riveting. Seems to me if you are using a flat bar on the surface to support the flat surface you would be better able to maintain a flat surface vs banging on the surface with a rivet set.
Anyway, didn't want to start a primer war, just stating my experience and presenting options. Agreed, use what ever technique produces the best results for you.
