It was a response to the person who complained about python's cgi being removed from stdlib and them wanting to go js or lua (both of which don't even have any supporting code for cgi)
The problem isn't that you can't write a CGI script in Python, or that it's hard to do so. The problem is that the Python standard library is being maintained under a policy of breaking new things intentionally every release, so nothing you wrote five or ten years ago works today. The `cgi` module is one thing that got broken, but there are a lot of them.
