OP is correct, you still can develop like this with PHP, and no the ship has not sailed for many.
You can have deployment pipelines etc, but if you like, you can still develop the ancient way - it still works.

Now you can put .py files into your www folder, like .php files.
One can also use old school CGI to serve their site, it’s super lightweight and you just upload the file at the right place, for almost any language. But that has been deprecated for the last 2 decades now.
It works for them, but I wont tell random people starting a business now to go with pen and paper, 99% of the time that would be a bad advice when there are much much better alternatives now.
