Not just recent, the pre-Biopace Polchlopek ones were aligned like everybody else, only Shimano had other ideas.

Idle wondering during a spin class: I know Biopace etc rings are meant to get you over the flat spot with less effort, but could you rotate a biopace ring 90 degrees to make the flat spot harder on a spin bike, and improve your performance on the flat spot while keeping normal round chainrings on your actual bike?
