It doesn't duplicate, it wraps. `sl-checkbox` is ultimately a `input type="checkbox"`, but wrapped in containers and exporting uniform props. For example `sl-checkbox` is a container with both a checkbox and a label container in it. And it exports a prop `size` which takes the values "small", "medium", "large", which is uniformly provided across Shoelace input components. It's a combo of (a) HTML lacks the features/ergonomics and (b) need to provide a clean-syntax API that extends HTML.
