I am generally not interested in the kind of granularity you are speaking of. If it is on the near term roadmap it will be a bullet point in one of the posts in the the /releases category. If it is not, then we get to it when we get to it; looking too far in the future is not practical.
If you want to influence that, pay for a hosting plan, and know that we give feedback from our enterprise customers the most weight: http://www.discourse.org/buy
