This actually reminds me a bit of CGI ( https://en.wikipedia.org/wiki/Common_Gateway_Interface ) or its later variants.

Personally, i think that PHP's request-response workflow is infinitely easier to deal with than that of servlets in Java or whatever abstractions other technologies out there have, even if only when scaling isn't a concern (which is perfectly passable for some systems out there).

My ideal language for getting things out the door would be something a bit like PHP, but with the standard library of .NET/Java (LINQ or Streams in particular), the wider ecosystem of Python, simplicity of Go and a decent type system on the top of it all, that'd process requests much like PHP does (or at least would only make you think it does, though abstractions that are leaky are arguably worse than none at all).
