Like was said in #2435, this is what people would expect. While we should note this in a compatibility section in the changelog, I do not consider this a breaking change since we should be free to adjust the help output as needed. We are cautious when people might build up their own content around it (like #3312) but apps should already handle this with `--help` so this shouldn't be a major change. We aren't offering a way for people to disable this, assuming people won't need to. Longer term, we are looking at support "Actions" (#3405) and expect those to help customize the flags. We'll need something similar for the `help` subcommand. Fixes #3440
