Everyone already has it... on Linux and Mac. It's pretty rare for it to be available on Windows.

That said I kind of agree. I like the idea of `just` but it does seem like they have just created a complicated DSL.

I think it is better to just write your infra scripting in a real language. I generally use Deno or Rust itself and a thin wrapper that `cargo run`'s it. Using Rust eliminates a dependency.
