Very often, a single user with a weak password has his account cracked and then a hacker can get a copy of /etc/shadow and brute force the root password.
This is incorrect. The whole reasoning behind /etc/shadow is to hide the actual hashes from normal system users. /etc/shadow is chown root.root and chmod 0400. Without root access /etc/shadow is not accessible.
