What about zio-cli, and zio-process? Are those considered sub-optimal for single file applications? Ngl, os-lib and mainargs from com.lihaoyi shortened my code by 4, and made it significantly less complex in my toy project --- even though they're not the same, not saying they are, I'm just playing around with different Scala frameworks.

Makes sense, why not

Sounds like a good thing to have, but what tools are missing? If we create a toolkit, I think we should at least give it a clearer name.
