I like this a lot. I would say that going with one of the existing standard libraries is a start - lodash is a good example. Another thing is anyone can roll most of these tools into standard libraries if the source license allows them to. So maybe some "rollup" packages are in order. You would get more than you need, but if you setup any sort of tree-shaking (which has been the focus of many build systems lately) then you can only bundle what you used in the end. One other thing that may be an issue is if you have two major libraries and each one is missing one function that you need - then you need both...
