It does seem a little silly, the readme does also mention it was written as a joke.

Was looking at ways to decrease logspam from ssh login bots some years ago, port knocking seemed like the most elegant solution. I ended up simply moving ssh away from port 22, the logspam disappeared.

I've used fail2ban in other setups, it also has the advantage of being easy to integrate with other systems such as wordpress, sftp/ftps, nginx, apache.
