Glad to hear these ancient systems are finally being replaced.
 * What will happen to the Chat extension?
 * If that's going to go too, what will happen to WikiFeatures?
 * You announced that the UCP will be ready in early 2020, and now you mentioned how two more systems whose migration was not communicated before will have to be completely replaced on the new platform, as well as building what seems to be a completely new profile system. Discussions was in development since about 2016, so should we expect no comments, walls and profiles on the "simple" UCP wikis announced to arrive in about 6 months?
 * Do you have any plans for a global feed of Fandom wiki activity and would it be publicly accessible on the UCP? I know newer MWs have the almost exact same IRC feed as the current one, but there are newer features for that purpose, such as EventStreams.
