Of course this is news. My friends and I have been talking about the removal of "is" for weeks now! Thanks for the status update. I was thinking that maybe it was just applications that could do it with the API, but I guess it was there in the UI for a minute before it got yanked...
Audio reappeared in my applications list (left-hand nav) this morning. It's not in the main applications list (when you click "Applications" on the left-hand nav). When I click it, it goes to the standard "Page you requested was not found."
