My only problem with jumping is that 99% of jumps will be done out of boredom.

This is exactly what it's going to be, since Yoshida did mention the word "Emote" in conjunction with Jump. So unless that changes, it is just an animation to make people not feel tied down to the world.

That was before 2.0 and the new engine was announced. If you've seen the video from the last letter, it is clearly not an emote. unless you can run "emote /jump" to be able to jump forward which sounds ridiculous.
