Portability and other constraints I've discovered with the shell have always been a sign I need to reach for different tool. Bash is so often a "glue" language where accessibility and readability are it's primary feature right after the immediate utility of whatever it's automating. Writing POSIX compatible scripts is probably safer and can be validated with projects like shellcheck.

That said - this is a neat project and I've seen plenty of "enterprise" use-cases where this kind of thing could be useful.
