Dependency minimalism (writing software that deliberately tries to have as few dependencies as practical) is a really underrated virtue imo.

Every single dependency is a risk that "something will go wrong" during someone's installation process. Installing projects with hundreds of dependencies and walking through errors can be incredibly frustrating.

I strongly agree! 
This is a very difficult task for humans because it would significantly decrease efficiency in practice, but I guess it is highly achievable with AI coder: “remove dependencies”
