alt Hacker NewsAll maintainers need to do is code signing. This is a solved problem but the NPM team has been actively rejecting optional signing support for over a decade now. Even so maintainers could sign their commits anyway, but most are too lazy to spend a few minutes to prevent themselves from being impersonated.
If the solution is 'maintainers just need to do xyz', then it's not a solution, sorry. It's not scalable and which projects become 'successful' and which maintainers accidentally become critical parts of worldwide codebases, is almost pure chance. You will never be able to get all the maintainers you need to 'just' do xyz. Just like you will never be able to get humans to 'just' stop making mistakes. So you had better start looking for a solution that doesn't rely on humans not making mistakes.
