I wish they had a separate Query Language list - it's weird seeing SQL sit between Python and Typescript...
I also think it would be a good way to introduce more people to non-SQL query languages (like Quel, PRQL, ISBL, jq, Alpha (even though it's still not been implemented), SaneQL, EdgeQL, and many more), because it generally feels like it's the only query language available ever... Which it's not.
I don't see why not. It has a sublanguage which can be used to query - same with SQL. You can do other things in SQL besides querying as well, so why not?
