Flag SubCommands in YAML?

Discussed in #3010

I saw that #1974 added support for sub-commands with a flag-format. However, they don't seem to be available when ingesting YAML?

I tried the following:

[...]
subcommands:
    - web:
        about: "web subcommand"
        short_flag: W
        long_flag: web
[...]

However, the keys short_flag and long_flag are silently ignored. Meaning, cargo run -- --help shows only web as a sub-command.

I expected it to show -W, --web, web.

We have decided to deprecate the YAML API. For more details, see #3087. If there is interest in a YAML API, it will likely be broken out into a clap_yaml and developed independent from the core of clap.
