[Question] Passing type and not using it in interface

[LukaszUrb]

Hello.

Path: src\shared\domain\events\IHandle.ts

Why do you pass type IDomainEvent in this file and don't use it at all?

import { IDomainEvent } from "./IDomainEvent";

export interface IHandle<IDomainEvent> { 
  setupSubscriptions(): void;
}

Maybe instead of

export interface IHandle<IDomainEvent> {

it should be:

export interface IHandle extends IDomainEvent
