For an intermediate solution, I shall accept the js-stuff, but I would like to stay consistent and only use our shell-rust integration tests. Also because what you implemented here is already possible with our current rust-cli.

I do think, however, that when we want to extend our integration testing suite, that a switch to js/ts is reasonable, but then with a holistic approach. :)
