I noticed there's no Hard mode category. Any particular reason?

Since nobody uses Dizzy in speedruns, I was thinking of a category where you would have to use Dizzy for the entire game. The only rule would be simple - you would have to switch to Dizzy as soon as possible in every world and then stay as Dizzy for the entire rest of the world. What do you guys think?

I have a run from January 2020 that has yet to be confirmed and that I've bested a few times since. Just wondering if any of the mods are still around or active.
