My favorite trivia is that busybox has built-in cgi-bin support (and `rclone serve webdav` seems remiss to not mention as well). `https://elixir.bootlin.com/busybox/1.37.0/source/networking/...`

Everything the post mentions is 100% true and well-reasoned, especially with the inclusion of pledge/chroot/etc. for dropping privileges.

There's two diametrically opposed deployment mechanisms:

1) stack towers of glop on top of each other until you're running a simple `echo "hello world"` on top of a docker container inside a vm in a proxmox server as part of a k8s cluster under a hypervisor running on remote compute...

2) just run `bash -c 'echo "hello world"'` and front it with CGI (stateless, single binary, yada yada yada...)

Take a peek at https://github.com/Domain/bash.cgi ... not that i'm suggesting that 'bash over busybox using cgi-bin' is the "proper architecture", it's more trying to illustrate that the amount of code that holds you back from being nearly truly "frameworkless" is tiny and easy to reason about.

For some of the internal tooling I'm doing for work, I've been tending towards:

    some-cmd [--json|--markdown] ...yet-more-args...

When you use the process and shell environment itself as a repl, you start trending towards `[--cgi-bin]` would "just" be another output type, and the ability (nay: foresight!) to ensure that your commands are independent, reproducible, and only depend on their input arguments leads you directly towards being runnable in both "hostile" (ie: firecracker vm / lambda-style) or very "comfortable" environments (ie: shell, debuggers, unit/integration tests).
