I don't think it's useless. You can use hyperfine to run multiple benchmarks at the same time, to get a comparison between multiple tools. So if you want it to work without quotes, you need to (1) come up with a way to separate commands and (2) come up with a way to distinguish hyperfine arguments from command arguments. It's doable, but it's also not a great UX if you have to write something like

    hyperfine -N -- ls "$dir" \; my_ls "$dir"
