as any?

We only "hide" them from the type checker if our propTypes are not as strict as the actual type definitions. Using propTypes with TypeScript requires an exact match e.g.

interface Props {
  options: { checkMe: number }
}

function Component(props: Props) {}

// rejected
Component.propTypes = { 
	options: PropTypes.object.isRequired,
}

// passes
Component.propTypes = { 
	options: PropTypes.shape({ checkMe: PropTypes.number.isRequired }).isRequired,
}

In that case they match so no need for any.
