Recommended style for long method generics.

In relation to rust-lang/rustfmt#6507,

pub fn cli() -> Command {
    subcommand("uninstall")
        .about("Remove a Rust binary")
-       .arg(
-           Arg::new("spec")
-               .value_name("SPEC")
-               .num_args(0..)
-               .add::<clap_complete::ArgValueCandidates>(clap_complete::ArgValueCandidates::new(
-                   || get_installed_crates(),
-               )),
-       )
+       .arg(Arg::new("spec").value_name("SPEC").num_args(0..).add::<
+           clap_complete::ArgValueCandidates,
+       >(
+           clap_complete::ArgValueCandidates::new(|| get_installed_crates()),
+       ))
        .arg(opt("root", "Directory to uninstall packages from").value_name("DIR"))
        .arg_silent_suggestion()
        .arg_package_spec_simple("Package to uninstall")
        .arg(
            multi_opt("bin", "NAME", "Only uninstall the binary NAME")
                .help_heading(heading::TARGET_SELECTION),
        )
        .after_help(color_print::cstr!(
            "Run `<cyan,bold>cargo help uninstall</>` for more detailed information.\n"
        ))
}

Which of these should be preferred? Rustfmt currently ends up with red because it never wraps method generics. If we allow method generics to wrap then we get cases like green. Should wrapping a chain be preferred over wrapping any of the method generics in the chain?
