Understanding <section> vs <div> for Better Accessibility

<section> vs <div>? 🤓 Hey all! A question for the Relume team - perhaps Dan when you get a minute? I fiddled with the MAST framework for the past week or so, and noticed it utilizes the <section> element for sections, which makes a lot of sense at first glance, first and foremost for increased accessibility. Is this something the Relume team considered in the past, or is considering for future releases? In your experience, are there any significant A11Y differences when using a <div> for sections instead of <section>?
