From the project docs

"There is no roadmap. I mostly implement the stuff which I need or interests me, or which gives me the opportunity to learn."

Pretty much says it all. Seems it was primarily written to satisfy personal needs, not be the end-all, be-all of professionally written software. It is, incidentally, potentially interesting to others who might want to learn from it, or use it, knowing the background.

So, you might cut the guy a break. The requirements for personal projects aren't the same.
