Interface isolation principle (ISP): it is better to use multiple special interfaces than to use a single total interface.
The dependence of a class on another class should be based on the smallest interface.
An interface represents a role, and different roles should not be assigned to an interface. Unrelated interfaces are merged to form a bloated large interface, which is a pollution to roles and interfaces.
