That would be a deer with venison that you can hunt. However, the deer quickly notices and can run away. And it's faster than a minecraftkin. So you need a bow and arrow or a trap. The coat or the antlers could also be useful. And the meat has a high saturation effect. What do you think?
New animals will take some time until the bee update and then the Nether update
in the Minecon yes was tuned which biom is to be revised as there are also new animals or one animal
First of all, Mojang should watch that the 1.15 update still gets good features, such as New cavern dungeons and then the 1.16 nether update has to succeed. I think a deer is relatively unnecessary, but more important are new weapons and tools.
Oh yes you could do a whole forest animal row with deer, squirrels, wild boars, foxes, …
Your description I find cool, as an extra feature, the deer could protect you from dangers (creepers, …) by running away and making noise! 😂😌
