Block would be too extreme for just four digits.

I'm confident that Visual Studio Code is supported, but I'm not sure about the other one. I'll have to think this through carefully.

I feel pretty confident about this one. I remember the rule is that you can use single-row functions in the WHERE clause without a subquery, but you do need a subquery if you want to use them in the HAVING clause. For aggregate functions, it's the opposite - you need a subquery in the WHERE clause but not in the HAVING clause.
