I like how every Common Lisp website doesn't even have an SSL certificate. Just started learning the language recently and it takes two clicks to get anywhere.
I don't see the relation between the web server and CL. Are you saying these sites are running off CL and would benefit from a certbot port, or were you just joking?
While I wouldn't be too surprised if websites about Common Lisp did the expected dogfooding, it was indeed a joke about certificates being a solved problem.
