Rust with Clap solved this forever ago.

Also - don't write CLI programs in languages that don't compile to native binaries. I don't want to have to drag around your runtime just to execute a command line tool.

Apparently that ship has sailed. Claude Code and Gemini CLI requires Node.js installation, and Gemini README reads as if npm is a tool that everybody knows and has already installed.

That's terrible, but at the very least there's the tiny justification that those are web API clients rather than standalone/local tools.
