You could make it dynamic with "bin -OpenAutoComplete" to have the binary output the Json. This would allow gradual introduction and backwards compatibility. It would also keep the completions up to date with binary versions, and still allow a shell to cache the Json. More importantly, you should consider other metadata before you go to far; binaries could carry their own documentation, licensing, dependencies... What should be in and out of scope?
