>The compiler should be able to eliminate the unused parts during compilation, it’s not like adding JSON to the standard library is going to make a “hello world” program bigger.
I agree. I would argue against keeping standard libraries terse as an appropriate goal for a language because terse (or alternatively, inadequate) standard libraries are exactly what necessitate third party libraries for common functionality, which in turn lead to this dependency hell that so many people dislike so much. Not to say that a standard library should do absolutely everything, but the more capable a language is out of the box, the fewer third party libraries a language ecosystem will come to rely on, meaning that methodologies will be more consistent in more code and dependency management will be simpler.
