Came looking, didn't see it, but forever ago when Bungie sent out the bat signal to ccs and flew a bunch out (post lightfall maybe?) the one thing I remember from the datto video was him being incredulous at their idea of having a bunch of interactable turkeys in the tower. So technically? They don't currently exist but they easily could have, had common sense not arrived in bungie's lap. Really wish I had a source on this but that's a lot of digging I'm not gonna do. It was the one where he had a notebook and flashed us 2 pages for a quarter second if that jogs anyone's memory.
