Which if the following is not true about reusing interfaces?

The statement that is not true about reusing interfaces is that interfaces require constant updates for every small change. In reality, one of the main advantages of reusable interfaces is that they are designed to be adaptable and help minimize the need for frequent updates across different applications. When an interface is properly designed with reusability in mind, it can accommodate changes without requiring constant revisions, thereby streamlining the maintenance process.

Reusable interfaces also promote consistency across applications, simplifying how updates are managed. If an interface needs to change, updating it in one location can reflect in all the places it is reused, reducing redundant effort and ensuring uniform application behavior. This principle significantly enhances efficiency in application development and management.

While it might seem that every small change requires updating interfaces, a well-architected system allows for flexibility and minimizes disruption. This is why constant updates for minor changes are not a characteristic of efficiently designed reusable interfaces.
