I was about to write the same thing. I like "done". The best libraries are the ones in maintenance mode, with long-term stability goals. The worst libraries are ones where the author(s) do a Major Rewrite every year or two. There is a widespread meme/trope about something being "dead". Whenever I hear someone saying that a language/library is "dead", I make a point of checking that person's credentials. It almost always turns out that these are not people who write big applications or well-known libraries, but rather ambulance chasers — constantly looking for the next shiny thing.
