   I took a look at potentially splitting this PR into two more contained ones 
between `EXISTS`/`NOT EXISTS`, and then a stacked `IN`/`NOT IN` on top, to 
reduce some of the surface area here.
   
   The reason I'm holding off on doing so, for now at least, is because the 
non-injective correlation bug, from your last failing example query, appears in 
both of the aforementioned shape categories. I'm going to stress test a bit 
more, and I can refactor for better composability afterward.
   
   On a secondary note, to make this a bit more robust, I'm working on 
extending our [fuzz test 
setup](https://github.com/apache/datafusion/tree/main/datafusion/core/tests/fuzz_cases)
 to generate random query shapes for groupless aggregates. I'll cross-verify 
against other engines to see where this breaks, and hopefully iterate from 
there.
