Fandom implemented Discussions because Yes, it is true Discussions feel completely separate from the actual site but I believe the engineers are working on changing that. Discussions got a lot of bad feedback from the users, too. I have no idea if Community Council members approved the idea of Discussions and if one of them tols you they would be breaking their non-disclosure agreement, which is a very bad thing to do.
 * 1) It's very hard to make a proper forum running on MediaWiki - their implementation is one of the worst hacks into vanilla MediaWiki and still contains tons of bugs they won't need to fix when they switch to Discussions.
 * 2) Making Forum portable would be hard, and if they wanted to add Discussions into an app it would be much easier to make a completely new RESTful API instead of the Nirvana or MediaWiki API.
