The new feature allows you to set sharp shading edges on models that are otherwise smooth shaded (accessed by Display > Object Display > Crease Edges), so models can have a combination of smooth and sharp features while still remaining low-poly. (The command is doubled up with Subdivision Crease Edges, which was already implemented.) This edge creasing is supported by several export formats.
In the screenshot, the model on the far right is shown as a low poly object with smooth shading and Crease Edges applied to get the proper look. (Left: flat shading, middle: smooth shading without creases.) Video here: https://www.youtube.com/watch?v=xYfX1HmzXqk
