What is an example of such a query? Maybe is it what @poonai proposed adding in https://github.com/apache/arrow-datafusion/pull/3473 / https://github.com/apache/arrow-datafusion/issues/2214?

I think this is coming from the ANSI SQL (Selective Aggregates).
https://modern-sql.com/feature/filter
https://popsql.com/learn-sql/postgresql/how-to-use-filter-to-have-multiple-counts-in-postgresql
PostgreSQL, SparkSQL and FlinkSQL all support this usage.
