That makes sense. I use Python the for most part. I feel like I have seen this happen with old libraries where they used to be very popular and maintained then became abandoned a few years ago.
That can be okay. Depending on the nature of the library it might legitimately be "done."
Personally, I would rather see this than a bug fix being committed every week. That makes me question how many more bugs there are and how much I'm going to have to babysit updating the dependency.
