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.

Best,
Ihor
