Bees to pollinate more then just crops

The pollination effect is exciting and inspirational for crop farms, yet still a bit limited. Lots of objects in minecraft can be bonemealed and would in the natural world also seem logically connected to bees pollinating. Bees pollinating such plants as bamboo, sugarcane, saplings, cocoa beans, berry bushes, and possibly grassblocks, could make for some very interesting experiments with farm designs, that do not seem overpowered either.. Also it is a little stramge that the flowers they would be pollinating in the natural world do not get pollinated in the minecraft world.
