The point of having a standard library is that it'd actually ship with the interpreter, so you wouldn't have to "get more than you need" - it'd already be there without having to download. Obviously there would be a period of time (years) whereby you would have to do a conditional download, but the longer term aim would be that it's already provided as part of the base language.
