First, I consider a single header library as a symptom from the lack of fine package managers for C and not as a feature. Such a form should not have been a norm at all. Also note that stb_image is extremely stateless. The documentation is not a must for stateless APIs because it is relatively easier to infer from the signature (of course you need to learn the convention, for example, to see that `int x, int y` etc. are out parameters and should not be NULL though). But many other libraries need states, and a proper documentation is required.
