Revamped Wool (+new Mob) And update idea

My Idea for Minecraft is to somewhat "revamp" the "wool system", the way I would go about doing this would be like so:

Default sheep would generate with "wool" (no longer the same as White Wool) which would be a creamy white colour with goldish streaks. Once you shared them they would drop this wool Instead of white wool (now crafted with white dye) White Sheep Would Now have a random chance to spawn like pink/brown sheep with the new wooled sheep becoming the default.

Along with this I also foresee The addition of the "Wooly Cow" from Minecraft Earth, Which when Sheared would also drop this new wool block, Along with 1.17's goats

Finally I Believe This Wooly revamp would give Mojang the perfect excuse to make terracotta and wool redyeable (ie: Could Make Pink wool/terracotta into brown wool/terracotta instead of having to use plane wool/terracotta {similar to vanilla tweak's Unerversual dying Crafting Tweak})

Also on an unrelated note A later Update (1.19/1.20) should be the "Bountiful Biome" Update Updating All The Biomes From The Minecon Biome Votes
