But I don't normally use the feature to debug Emacs's C code. 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.
