Ideas and features I want to see in 1.21

Ibxtoycat made a video called Minecraft needs to change this in 1.21 and I thought it brought up a lot of good points. Like a trial spawner has a raid like boss bar to show how many mobs are left from that spawner. And the more chill side of mc. All they get out of it is a few trims and pots. Why not add a new music disc like all the other significant updates got or new tool, maybe give the mace another function like mining in a 3x3. This is probably asking for quite a lot considering what we already got.
