> But it’s not. Because if you’re not adding new features and pushing code changes every day, your project is abandoned, dead. To quote another thread from two minutes ago: “I’m quite sad to see the end of Moment.js” In this case, the reason why Moment.js is "dead" and not "done" is because it has fundamental flaws in its design: Mutable objects + huge bundle size which doesn't work well with tree-shaking.
If you fundamentally and incompatibly change it's design then it's an entirely new product. Calling that "Moment Version 3" doesn't mean anything.
Trust is major factor when depending on third party libraries especially in the JS ecosystem.
