Should I use ProptTypes for props I pass through a React component?

Should I use PropTypes for props I pass through a React component to a child component, but don't actually use within component itself?

In the following example, Component2 would have PropTypes for the props received from Component1, even though Component3 is the component using the props.

<Component1 someValue=someValue">
  <Component2 {...props}>
    <Component3>
      <div>Hello World! {someValue}</div>
    </Component3>
  </Component2>
</Component1>

In my opinion, its enough to declare propTypes for props that Parent component is using and if rest of props is just passed through, then it's Children component responsibility to validate them. This way you avoid repeating yourself and still get error validation.

you can actually write something like this. It makes the code more readable and instantly tells some other developer about your intent 

MyComponent.propTypes = {
 someValue: PropTypes.string,
 ...Component2.propTypes
}
