I also fully agree with the author and I am usually following a similar practice. The libc is the weakest point of the C programming language, outdated, bad naming conventions, and in some cases harmful APIs. It also has its merits, simplicity and availability, it is good as a fallback, but I think it is generally preferable to have a full API coverage when using a framework, including basic things such as printf/malloc/fopen as there are better ways to make those and it is quite important to maintain similar convention across the whole codebase.
