Why is it not on speedrun.com yet?

Its a very popular game to speedrun and for some reason they didn't add it yet.

I know they have a "reason" why they did not add it but in my opinion its a really bad response

The reason why they didn't add it is that it's short/trivial but at the same time but Minecraft classic with speedruns that are literally 1 second

I understand speedruns stance, but exceptions need to be made for games with “cultural significance”, or popularity. I understand the problem of cost but that’s at least 160+ people who may not be a part of the site already now being involved in the community, and maybe some of them leave but maybe some will stay as well.
