Yes.  It's there for convenience only, since people often want an
element that does exactly this.  If we didn't provide it explicitly,
they'd just awkwardly wrap their <dialog>s in a background element

Can you describe a use-case for putting the ::backdrop somewhere other
than directly underneath the dialog/fullscreen element?

Both of your examples would be done by using elements that are
children of the <dialog>, and perhaps just positioned explicitly
