A client code may abstract some specific functionality to an interface, and define the definition of
the interface as an SPI ([Service Programming Interface](https://en.wikipedia.org/wiki/Service_provider_interface)
is an API intended and open to be implemented or extended by a third party). Another package may
implement this interface definition with a concrete logic, which will be injected into the client
code at runtime (with a third class, injecting the implementation in the client) or at compile time
(using Plugin pattern with some configurable file).
**Programmatic Example**
The Separated Interface design pattern is a software design pattern that encourages the separation of the definition of an interface from its implementation. This allows the client to be completely unaware of the implementation, promoting loose coupling and enhancing flexibility.

In this way, the Separated Interface pattern allows us to decouple the interface of a component from its implementation, enhancing flexibility and maintainability.
