Sometimes I need to create the props at a different level/location and not directly on the component. The interface for the (class component) props is then very useful.

This is no different when using Hooks. You specify the type of props as the type of the first argument in the functional component:

  function MyComponent(props: IMyComponentProps) { ... }

Where the type definition of IMyComponentProps resides doesn't matter, you can import it from anywhere.

I was simply pointing out that explicitly defining an interface is not necessarily a downside.
