`clap_generate` originally intended to be "generate anything". With `fig`, we already broke one part out. With #3174's man support, we are also looking at keeping it separate: - More freedom to iterate on the API - Uniqueness (and potential weight) of its dependencies - man generation is normally more for distribution while completions are a mix of being distributed with the app or the app generating the completions (which will be exacerbated if we move most completion parsing logic to be in Rust) So `clap_generate` is having a lot more limited of a role than the original name conveys. I worry the generic name will be a hindrance to people discovering and using it (yes, documentation can help but there are limits). I hesitated because we are on the verge of releasing 3.0. However, doing it even later will be even more disruptive because more people will be using it (crates.io lists ~70 people using `clap_generate`). To ease things, we are still releasing `clap_generate` as a wrapper around `clap_complete`.
