Wookieepedia never enabled it because it felt that third party sources were best for fandom discussions. They use the old forums for administration of the wiki.

So once again, the only issue is the loss of WikiText and how will Discussions evolved it's media rich and inter linking features (or whatever other features you communities use).

And if admins don't want to babysit, then find a babysitter who will follow and enforce rules and guidelines that will improve the overall wikia community experience.
