Personally I don't think it's worthwhile to use a large number of micro-libraries, because of the huge overhead that comes with it. Every library has slightly different naming conventions, you have to be sure that they play well with another (e.g. compatible collections and Promises implementations), you don't have a single point to look for documentation and so on. Also, if you want to optimize for file-size, you won't get very good results with a collection of micro-libraries. A compiler like Closure is capable of inlining functions and removing unused code only as long as you have all of it in a single file as private functions. But when every library exports all its features, Closure is not able to optimize them properly anymore.
