AFAICT Phillip has explicitly promised he will maintain it (or if he doesn't, I expect that he would gladly do so if you asked). This has always been sufficient as a "guarantee" that a new module isn't orphaned.
I'm not that worried about maintenance of the tool itself, but supporting "it's magic! (as long as you use the correct combination of one-letter options)" stuff is no fun at all.
