This is meant to be one avenue to help people with #3822

With the new `ArgMatches`, we need to know what the inner type is.

Unfortunately, clap-rs#3142 didn't list use cases for this.  We dropped the
`Option` alias changing `T` but we still have a `Result` in there that
is aliased.

One potential workaround if people need it is if we add an attribute to
specify the `get_many::<T>` type.  This would also help with
`ArgAction::Count` to support more data types.
