I use it to understand what the C code will do if some Lisp code calls it, in greater detail than if I just read the doc string. I use the feature in the same way to understand Lisp-implemented functions, too. This aspect of the feature is useful even in prepackaged Emacs distributions where I don't plan to debug or change either the C or the Lisp code. Of course this aspect of the feature is not useful for everybody. However, it is useful for some people and that provides a case for adding it.
