From my point of view the problem is not micropackages, but the constantly changing micropackages making the foundation of your software ever shifting around. The problem with leftpad was not any problem with the library itself, but the library changing (in this case getting deleted). I posit that embracing the culture of vendoring dependencies, and even fully absorbing them to your projects, leads in the longer term healthier ecosystem. Again leftpad, if everyone had vendored it then it would have been largely a non-event. Of course this way of thinking puts much higher demand on correctness and also probably some novel innovations regarding patch management when as a library maintainer you can not just rely on ability to push out new versions from your cathedralesque project.
