I'm surprised to see that the compiler is written in V (https://vlang.io/). Last I heard, V was vaporware, and a lot of its claims about performance etc. ended up being "todo" items rather than facts about the language as it actually existed. But that was several years ago; has anything changed?
Otherwise, fun project! I could see this actually being useful in some niche cases, e.g. generating scripts that need to work on some exotic architecture that has a POSIX Sh implementation.
It might also be useful for writing interactive shell "plugins" that set up things like a fancy PS1 prompt.
