    If we merge this change together with #3764, we would check it with tests that use distinct
grouped window aggregates. 
    But you are right, it might in fact make sense to test the `GeneratedAggregations` class
generated by the `CodeGenerator` individually in a unit test. I wouldn't make this as part
of this PR though.
