It's the same argumentation: It's already easy enough to do this in C, with 1 to 5 straightforward lines of code. When you provide an API, where to stop? When an API provides two similar functionalities, where one can be coded using the other and 1-5 extra lines of code, one of them is redundant. - Once we have memcpy, is it worth having strcpy and stpcpy? Normally no. But there are so many uses of memcpy that adding strcpy and stpcpy was worthwhile. - Once we have strpbrk, is it worth having strcspn? I would say no. strcspn is only there because it predates strpbrk. - Once we have regex_quote, regex_quote_anchored is redundant. The drawback of a large API is that it's harder to keep in memory.
