So say you need a particular function. You end up importing this entire module, which has dependencies that also are defined in large-granularity terms (other modules) that have their own dependencies. So to use one function, you get saddled with a whole heap of dependency overhead. Just playing the devil's advocate here: in this use case, why not just write the function yourself?
