It would be great that just like the super wall papers enabled, they will enable Always On Display (AOD) for everyone and that each one decides whether to use it or not. I have tried many roms that have it enabled and the battery wear is practically the same
Thank you for your uneducated opinion. Unfortunately, we have no plans of doing so, because we know better, Xiaomi does as well.
However, you can share your opinion on the official Mi Community. Good luck.
