We need this category it's a awesome category we need this on bedrock edition

I'm not sure what this new category would entail, but I think your best bet to get it added is either posting this on the game's forums (explaining the rules for the category), or alternatively you could also join their discord server and ask the community there instead if they'd be interested.

EDIT: Digging around for a bit, I found a thread that already had a similar question: https://www.speedrun.com/mcbece/thread/sqie8

Not happening and never will happen unless someone can give us the technical knowledge to do seed manip and stuff.
