The intent of the granularization was to reduce header size by avoiding code we don't depend on. There is nothing wrong with including more code if you depend on it. That will likely make the average size of headers smaller, since we avoid duplicate implementations that way. FWIW I wouldn't be against merging some of the headers (e.g. `for_each.h` and `for_each_n.h`), but that's a different project.
