New characters in the game

Hello,
I would like to ask if you would consider adding two mobs that were originally planned for Minecraft but were later not included in the game.

The first one is the Iceologer (Ice Pillager), which I think would make snowy mountains more interesting and fun.

The second one is the cave mob that is afraid of the dark, which was shown during the update when you introduced the Allay. I think this mob would make caves more exciting.

I would be very happy if these mobs could still be added to Minecraft one day.
My name is Hugo.
