Are you still coding to support Internet Explorer? All browsers have supported details/summary since an Edge switched to Chromium in 2020.

While it’s good to use well-implemented semantic elements when possible, there are still plenty of places where either the built-in browser behavior isn’t actually very accessible (like native form validation), or where you just can’t avoid it (using aria-disabled instead of disabled for submit buttons, setting aria-pressed for toggle switches, setting aria-expanded for buttons that trigger modals, situations where you need aria-hidden/sr-only, etc).
Though once popovers and the invoker command api hit baseline widely available, we’ll be able to drop some of that.
