shadow 4.0.8 and it's etc/login.defs.linux

I knowticed the manual page for login.defs says:
      "Much of the functionality that used to be provided by the shadow  pass-
       word  suite  is  now handled by PAM."

su and login now report:

login also gives those configuration errors.

Perhaps those lines should be removed from /etc/login.defs?
Should they not already be removed from the default
configuration files etc/login.defs.linux in the shadow 4.0.8 tarball, please?
