In fact this should be the key selling point for stdlib to JavaScript. It actually saves money from their employers if trivial functions are mostly in the same place.
However pushing a stdlib is difficult there is a lot of hate for Python's "kitchen sink" library in JavaScript world which is totally misplaced. It maybe founded on fact that you should then minify the whole package to use one function in it, but this could be solved with dead code elimination (with proper type checking) in the minifier.
