That branch is around for a very long time. The last attempt on it was back in December [1]. However, all the progress was only in tests, not in actual code. As I mentioned in the discussion about using properties instead of overlays, I prefer to modify org now rather than waiting for someone to finalise and merge that branch. Also, text properties appear to use less memory.
