I don't really have an OSX computer to use it on, so it's not that useful to me. I could probably make the same or better in a few hours.
Not sure exactly what you mean by wrong or meaningless programs. (edit3) I'm not sure it's possible to write a meaningless SQL statement.
Edit: it seems like the authors don't see it as that useful. I think the page said they are still looking for use-cases, or something. Have you contacted them?
Edit2 (fta): "However, as of Jan 2019 we’re tabling the project until we have a concrete, motivating use case to inform further development."
