Exactly. They were introduced to prevent sloppy callers from passing NULL to the &end parameter to underlying strtoul(3). The first thing that came to my mind while reading your message up to this point was "why not use them more, tighten them, adding different variants if necessary, instead of introducing an entirely new set of functions in a new namespace?"
