Add a gondola to Minecraft

I've seen players riding pigs in boats tethered to Happy Ghasts and sulfur cubes, and it looks a bit awkward. I think a new entity called a "gondola" that can be used as seating is needed. Gondolas can be crafted with wood and wool, and are slightly larger than boats and minecarts, but they have no means of movement on their own. Instead, they can be led, and when led to a mob, they will hang below the mob and move together. Gondolas can carry about four people, making them ideal as a mode of transportation. Please consider implementing them.
