I don't even play Java Edition, but just look at their category extensions. It would be a lot more interesting if you had some spice in the Bedrock speed running page.

I think it would be fun if you banned conventional death methods. Maybe no structures, random seed, no lava pits, no drowning, and no pvp. Then people would have to be creative and maybe suffocate or do fall damage. And coop could be interesting for strategizing what's faster for everyone to die.

I think it would be good but only really on random seed and maybe no structures. Also a coop version could be funny if it was capped at like 2 players.
