True or False: The default application overlay can be deleted.

The assertion that the default application overlay cannot be deleted is rooted in the design principles of the Pega platform. The default application overlay serves a critical purpose as it contains essential configurations, rules, and user interface elements that are foundational to the operation of applications built on Pega. This overlay ensures a baseline for features and functionalities that can be inherited and extended.

While it is possible to create custom overlays to enhance or modify the default behavior, the integrity of the default application overlay must be maintained. This design choice aids in ensuring consistency, stability, and predictability across applications developed within the framework, making it essential for development teams to rely on it as a starting point rather than deleting it outright.

Modifications can be made to the default overlay, and custom overlays can be created to suit specific business requirements, but outright deletion is not permissible. This design approach aligns with best practices in software development, ensuring that applications remain robust while allowing necessary customization through overlays.
