I think it is more like optimist, pessimist and realist.
From what I learned some time ago, it is not likely to be implemented and period. Explanation was that there is a huge difference between the android and the SFOS bluetooth implementation, so that a bridge can not be easily developed.
As I know SFOS I can conclude that it will be never implemented. I wish they prove me wrong, but for now I stay at realist position.
