No, many are truly abandoned.

I have this all the time. Any new rust project and you have to wade through a bunch of once-great crates.

But that's because rust is new. The initial surge over produced solutions to, say binary serialization, and under produced, say, good geodesy libraries. And many many were abandoned. Go to any of the "are we X yet" sites and you'll see many crates that are clearly not finished or advancing which were recently considered SoA.
