I strongly agree with this. At $WORK I usually work on projects comprising many small bits in various languages - some PowerShell here, some JS there, along with a "build process" that helps minify each and combine them into the final product. After switching from shell scripts to Just and having to deal with a ton of issues on the way (how does quoting work in each system? How does argument passing? Environment variables?) I simply wrote a simple script with Python, UV shebang and PEP723 dependencies. Typer takes care of the command line parsing, and each "build target" is a simple, composable, readable python function that takes arguments and can call other ones if it needs to. Can't be simpler than that and the LLMs love it too.
