The follow-on question is therefore, are they going to save more time in the long run by writing poorly optimised queries for a particular quantum hardware stack (that we assume as being easier/faster to write), rather than writing highly optimised queries on classical hardware. Writing a garbage SQL query and getting it back faster might be worth it over optimising it - especially if the questions aren't regularly repeated.
