This taunt has been in the workshop for a long time, and the creator has made several other taunts that have made it into the game, so there's not much reason for it to not be in the game. Or is there? The reason why it hasn't been added is simple, there's no music. Now, it might sound dumb at first, but hear me out. With all loop taunts that are dances, they have music. But this doesn't. It would be pretty weird if there was a fourth all class dance taunt with no music, and that might be the reason why it hasn't been added. Now, this is my favorite taunt in the workshop right now, and I would love to see it in game, but the lack of music is stopping it from getting in the game. Now maybe i'm wrong. Maybe the TF team hasn't added it because they just don't like it, but if the creator was to add music to it and it got seen by the team, I think it would have a pretty high chance of getting in. So, hopefully the creator can see this, add music, and then Valve adds it... If there's ever another update...
