I use Jekyll for a static site and I guess I just don't really understand why it needs further development. I haven't upgraded my version of Jekyll since I think 2017 because it does what it says on the tin.
The stability is precisely what I like about Jekyll. I can come back to a website I haven't touched in years and update it and it works. It's so rare for software to work like that.
The latest version of GNU sed is almost two years old. Does that mean it's time to ditch it for the latest rewritten-in-Rust tool du jour? Of course not.
Infrastructural software such as Jekyll should be finishable.
Yet Jekyll just doesn't work for lots of other people. That's why vital software dependencies always need further development…because over time they properly service a smaller and smaller subset of users—unless we're talking about an extremely specific single-use library of some fashion. That's not what Jekyll is!
People should use something else if Jekyll doesn’t fulfill their use case. Jekyll does what it is supposed to do very well. It is refreshing in the software world to have tools which are not always changing from under you.
Sometimes it's ok for software to be "done".
