In an Aggregate, hidden columns are still considered how?

In an Aggregate, hidden columns are included in the logic of the query but are not included in the output that is returned to the client or end-user. This means that while these columns may not be visible in the result set, they can still play a crucial role in how the data is manipulated, filtered, or processed within the Aggregates. For example, hidden columns could be used for intermediate calculations or as filtering criteria, allowing developers to maintain the necessary logic without cluttering the output with unnecessary information.

The distinction lies in the fact that while the hidden columns contribute to the underlying data processing and the functionality of the Aggregate, they are deliberately excluded from the external output. This allows for cleaner data presentation while still ensuring the full flexibility of the logic being applied in the background.
