It isn't obviously complete either, and definitely still has bugs. And there are significant changes on master that haven't made it into a release yet. I think it is more that the maintainer(s) no longer have a lot of time to put into it. Which is fine and understandable. Maybe eventually a fork will gain enough traction to take over, or maybe one of the alternatives will become more popular, or maybe the maintainer will come back, or pass it on to someone else.
