Before #2005, `Clap` was a special trait that derived all clap traits it detected were relevant (including an enum getting both `ArgEnum`, `Clap`, and `Subcommand`). Now, we have elevated `Clap`, `Args`, `Subcommand`, and `ArgEnum` to be user facing but the name `Clap` isn't very descriptive. This also helps further clarify the relationships so a crate providing an item to be `#[clap(flatten)]` or `#[clap(subcommand)]` is more likely to choose the needed trait to derive. Also, my proposed fix fo #2785 includes making `App` attributes almost exclusively for `Clap`. Clarifying the names/roles will help communicate this. For prior discussion, see #2583
