I think adding isIndented prop is unnecessary, as I think all that content should have already been intended nicely and by default, without any extra prop. I mean indentation is great, I'd leave it there by default, just adding a prop to do so is unnecessary. Otherwise 👍🏽 ❇️

Just a note that according to the design changes, KSM feature won't need this component anymore.

I updated it to be true by default in ExpandSection. That way it'll be available if needed, but otherwise we won't have to worry about setting it each time. Thanks for pointing that out!
