That's pretty good. Seems like a good reason to add an -f alternative to -q to provide an sql file. In fact, now that I remember, it has happened that I'll be provided a CSV, so I write this big query. Then, from analyzing the results, they'll tell me they made a mistake with the CSV they gave me and provide me with a corrected one. They'll use a different name to avoid confusion in not knowing which is the bad one and which is the corrected one, and I just change the file in the assignment and rerun the same SQL.
