More Forest Mobs in the Taiga Biome

Since the taiga biome is a very cool area in the game, I think that it would be nice to have some new forest-related Mobs added to it. The ones I was thinking of would be maybe some deer, maybe some bear variants. Adding deer/elk would be an awesome addition to the game because it would provide a unique source of food for the taiga and also just for aesthetic purposes. Maybe it drops antlers when it dies, and then you could hang that on your wall, or use it for crafting some other item. Adding more variants would be nice because of how there is already a polar bear variant and it doesn't make much sense why it is the only existing bear in the game. For example, there could be a black bear and a grizzly bear. The black bear would be less hostile than the grizzly, like in real life. the same mechanics would be applied from the polar bear to these bears, so this would be easy to implement. Maybe make it so that the grizzly could attack even without a baby next to it, and that it could be random, too. This would make a grizzly bear encounter much for frightening because there is some chance involved. (Maybe this could teach kids not to go up to wild bears). Adding bears and deer would make the taiga a much more interesting biome. especially bears, which add a sense of actual danger to wandering into the forest alone. Whenever I walk through a taiga biome in Minecraft, I feel like it is empty. An addition like this would hopefully fix this problem.
