Maybe improve the forests?

I played a better forest mod, and it was great. The trees were much bigger and better, there were birds and squirrels, and I just liked it a lot. The birds even had nests with eggs in them! I think that Mojang could improve the forests, even just a little bit. This would be the perfect opportunity to improve all forested biomes, and possibly add treetop villages. Some extra foliage could make the environment seem more alive. Mobs like deer would be the best. I think that brown bears would be nice, as well. That birch forest art we saw that was planned for 1.19 could be added. Fireflies could be added for ambiance, not for frogs to eat lol. There could be huts in the dark oak forest that have wizards living in them, maybe the Illusioner (about time to add it, as well). And a forest boss: that would put the whole thing together. While you're at it, maybe make trees naturally replant saplings, without the player. Mobs should also breed naturally. Just some simple fixes could make Minecraft a much better game (it's already really good, but could be better). And lizards! They NEED to be in Minecraft! Bonus: Striders have a 1 in 4 chance of dropping Strider Feet, a new kind of boot that allows you to walk on lava. You would have to sacrifice protection to walk on lava, but it's worth it.
