Your first example sound very sensible to me?

Using new technology in something small and unimportant like a setup script is a perfect way to experiment and learn. It would be irresponsible to build something important as the first thing you do in a new language.

For your own use, yes.

But if you're working with others, you should default to using standard industry tools (absent a compelling reason not to) because your work will be handed off to others and passed on to new team members. It's unreasonable to expect that a new Windows or Linux sysadmin or desktop support tech must learn Rust to maintain a workstation setup workflow.

agreed. I think if we all went with this HN mindset of "html4 and PHP work just fine" we wouldn't have gone anywhere with regards to all the technical advancements we enjoy today in the software space
