What seems a little odd to me is that in the first chapter of the announcement Sigma specifies this is an issue with the new Canon EOS 5D Mark IV.
But when you read the full announcement, they are also saying you could face the same issues with other Canon camera bodies as well. Here’s the full announcement Sigma released.
From Sigma

- MO (Manual Override) function is unavailable with this camera (Full-time Manual function can be offered).
- When using a SIGMA interchangeable lens for EOS, setting the corrections to [Disable] is recommended, as “Lens Correction” functions of the camera, such as Peripheral illumination correction, Chromatic aberration correction, Diffraction correction and Distortion correction are not supported.*
* If those functions are activated, the performance of lenses may not be accurate.
