The main benefit of hiding columns in an Aggregate is that it simplifies the output. When working with data in aggregates, particularly in situations where only specific information is needed for display or processing, hiding unnecessary columns helps reduce clutter and makes it easier for developers to manage the output. A simplified output streamlines data handling by providing only the relevant fields needed for further operations or for display in user interfaces. This clarity not only improves readability but also makes debugging and maintaining the code more efficient.

While performance might be a consideration in some cases, the act of hiding columns does not inherently improve the performance of the application itself; it is primarily geared towards making the data presented more manageable and relevant. Additionally, while security can be a concern with sensitive data, hiding columns does not automatically add a layer of security, as data can still be accessed through other means if not properly secured. Therefore, simplifying the output is the most direct and relevant benefit of this action in the context of working with aggregates.
