At least OpenGL ES would be covered in that case, as flat shading only exists in OpenGL ES 1 which has no shaders. I think it would be reasonable to re-emit the shader state (or maybe just the varyings) when the primitive type changes from points to non-points. It virtually never happens that the same shader combo is used for points and non-points.
