Dear all, Jambunathan (like anyone) is free to fork the code, to build a community around his fork and to submit his changes to Emacs. He has commit access to Emacs, so that should even make things easier for him.
This is free software, and the ability to fork is what makes sure we are all focused on software, not on personal issues. I am not actively looking for a new maintainer right now, I'm focusing on releasing Org 8.0 -- like all other contributors. I've been long thinking of stepping down, but I don't want to make this move before I have found someone me and longstanding contributors feel comfortable interacting with. Stay tuned! Thanks, -- Bastien
