More bear variants!

Currently in minecraft there are two bears: The Panda Bear and The Polar Bear. Why not more bears like a black bear or grizzly bear? It would be so cool to have a grizzly bear in a taiga forest, or have a black bear in taigas or other forests! Having the grizzly bear as another hostile (or semi-hostile) mob would be amazing seeing as we haven't many hostile mobs in recent years. And with the black bear, they could be semi-passive, they would be hostile based on conditions filled maybe! Personally, I just really would love more bears as I already love their models and would love more mob variations.
