> Counting elements within an array is a common use case. ARRAY_SIZE ensures the input to be an array and then returns the size.
> Other DBRMS like Snowflake supports that as well: https://docs.snowflake.com/en/sql-reference/functions/array_size.html. Implementing that improves compatibility with DBMS and makes migration easier.
