Poll: Is Three Jokers Canon? (Patreon)

As I'm finishing up the Rebirth re-read and cleanup, I got to Batman: Three Jokers, which I placed just after Joker War. This obviously does not fit here since some characters are dead in main stories and others are given personalities or roles that do not match their respective series (Batgirl, Red Hood, Batman, Gordon, etc.).

I'm considering moving this to the Optional page, but wanted to get all of your opinions first. Should this remain on the main order (moved further up where it may make more sense) or should it be kept separate (it is a Black Label series)?

Feel free to answer in the poll below and add any comments if you want to explain your answer.

P.S. I'm not fully caught up on current DC books, since I've been re-reading Rebirth, so maybe this comes up again later on. If so, let me know in the comments.
