Looks like you are inventing history.
mkdir() has been introduced in order to overcome a security problem.
mkdir before has been a suid-root program that first created an empty directory
node, then chown()d it to you and then created hard links to . and ..
This yould be used to let mkdir(1) chown /etc/passwd to you....
