Mob Spawners

I would like to  propose to change a look of minecraft mob spawner structure. New caves and cliffs update is amaizing but when you upgraded underground mineshafts you forgot about second underground structure :

- Mob spawners

When i was flying in experimental snapshot 1.18 i saw rly beautiful caves mixed togheter waterfalls and big underground lava lakes and at the end of one cave i saw the tiny and ugly box that looked the same for many years and i think that it should be included in Caves and Cliffs update.

Sincerely for the minecraft team :
