Unfortunately this makes unfamiliar components hard to understand since a prop might configure the appearance of the <Card> OR define its content.
The Named Children pattern helps with the mixing of concerns. Instead of setting children as content it's set as an object that maps section names to content. This approach separates content from config making it easier to guess each prop's purpose.
The Named Children pattern is a promising approach to separating concerns in React Components making them easier to read and easier to change.
