There's no way I'd ever import a tiny library like that. Verifying that a library does what I expect it to do, uses an appropriate license for my project, isn't likely to break my project in the future, etc., is a fair bit of work, and it only increases as more tiny packages are added. The worrying over increasing the size of the dist folder is a symptom of using a bad package manager. I do believe that packages shouldn't be bloated, and should mainly focus on a single goal, but that goal should be at least somewhat broad in scope. Manipulating strings is a good objective for a package, but changing the case of strings seems too small to be worth it.
