The last song on SABLE, FABLE, could it be Justin saying goodbye to writing new music?

I know its a long shot and maybe a ludicrous assumption, but its making me a little anxious seeing the last song on the new album named Au Revoir which means goodbye in french, I have a tiny doubt that it could mean Justin saying goodbye to us and music. Bon Iver has been a really important part of my life and I would be deeply saddened since I discovered their music like 3 years ago only. Not saying it for sure means something like that but I just wanted to share.

Do you ever get anxious at the thought of someone retiring from music or any other thing?
