There are a lot of knowledgeable authors on WoWInterface that could probably contribute, but to me it seems like almost nobody even dares to get involved with it
I personally never used Carbonite, but it looks like a very big and complicated project and definitely would be a lot of work to update and maintain it
There could still be a possibility for funding it with Kickstarter or Patreon looking at other projects, but maybe that would only help if there's one author taking all of the responsibility (and money), instead of a team doing it for free
