Yeah, the inertia is the real killer here. I'd love to see a fully embedded solution (particularly given that ecosystems like Go and Rust discourage sidecar files like manpages), but thus far the only one I've really seen is individual tools supporting a `--completions=SHELL` style argument that spits out an `eval`-able script for the requested shell.

The real dream would be some kind of standard way for a program to indicate that it's opting into more intelligent CLI handling without any execution. I've thought about trying to hack something like that together with a custom ELF section, but that wouldn't fly for programs written in scripting languages.
