What ever happened to the Dread language?

I remember the narrative devs talking about writing a unique language for the Dread, and that players could eventually discover how to interpret the language to know what they were saying. The Raid exotic lore tab supposedly had a clue, but idk if that ever went anywhere. Was a Rosetta Stone ever found in the Pale Heart, or was it a dead end? Has anyone cracked the spoken language yet?

Edit: I already deal with enough negativity in my life. Save your “game bad” and “devs fired” comments for another post.

Looking for actual answers please.
