It works on a level outside the JS library ecosystem: if people are judging potential new employees by their GitHub profiles, and that is resulting in people publishing all sorts of crap on GitHub to make themselves more employable, then eventually the reputational value of having published a JS library will go to zero (possibly even negative). Instead, employers will look for better indications of programmer quality, perhaps "Does anybody use your library?" Eventually some of the savvier programmers will realize that, they'll work on targeting real needs more deeply and really solving them well, and the huge mass of mediocre JS libraries will be replaced by a few good ones.
