Not to mention maintenance. Low-hanging fruit here: left-pad, depended on by fricking everyone, <em>is owned by one guy</em>. That is not how you build a serious utility library that people should actually be using in real products. (You also probably shouldn't license it under the WTFPL, but that's another thing). When you aggregate under a common banner, you get maintainers for free and your project might have a bus factor better than 1.
