} The calls exist and are being used (properly) for the stated reason.
} Why would you want to remove them?

     Because if the application happens to iterating a database by
using getgrent() or getpwent() at the time it makes a call to libwrap I
wouldn't want its pointer to be reset.  I have no idea why an
application would do this.  However, I don't think it is up to me or
necessarily up to any particular library to make this choice for it.
