Why is it important to avoid feature-to-feature dependencies in Sitecore Helix principles?

In Sitecore Helix principles, it is crucial to minimize feature-to-feature dependencies in order to ensure that dependencies remain stable and non-cyclical. This principle promotes a modular architecture, where features can be developed, tested, and deployed independently. When features are interdependent, changes in one feature can inadvertently affect others, thereby increasing the complexity of maintaining the system and reducing overall stability.

By having stable, non-cyclical dependencies, development teams can work on different features simultaneously without risk of conflicts or failures due to intertwined functionalities. This modular approach aligns with the Helix guidelines that advocate for clear separation of concerns, ultimately leading to better maintainability, easier testing, and a more flexible system architecture that can adapt to future changes with less effort.
