Example: a single `Remote` class controls only one `TV` type - separation adds no benefit, only a redundant abstraction. --- ### 2. **When There Is No Need to Combine Variants** Bridge is useful when you need to freely combine different types of abstractions and implementations (for example, different remotes + different devices). If there are no such combinations, the pattern loses its point - **plain inheritance or composition is enough**. --- ### 3. **When the Code Is Small and Rarely Changes** Bridge adds at least **two levels of hierarchy** (abstraction and implementation). In small projects or utilities, this creates **unnecessary cognitive load**: understanding the architecture takes more time than it saves. --- ### 4. **When the Abstraction and Implementation Are Naturally Linked** Some objects are by their nature tightly linked (for example, `Order` and `OrderStatus`). Artificially splitting them through interfaces can lead to **loss of clarity and redundant code**. --- ### 5. **When It Is Simpler to Make Changes Directly** If you only need to add a single new implementation, introducing Bridge for that is **over-engineering**. It is simpler to add a class or a field than to create two hierarchies. --- ### 6. **Conclusion** Bridge is worth applying **only** when you genuinely need: - independent evolution of the abstraction and the implementation, - multiple class combinations, - or swapping implementations at runtime. In other cases, **it only increases complexity, the number of classes, and the level of abstraction**, without delivering architectural benefits. **Summary:** Bridge is redundant when the system is **simple, static, or does not need independent layers**: then plain inheritance or composition is simpler and more effective.For the reviewerNote to the moderator (optional)Visible only to the moderator.
