Yes, though you'd just write the selector explicitly as ":scope".  I
believe it's a relatively minor issue compared to the larger
non-intuitiveness of @scoped being a filter rather than a scope.

I think it's pretty easy to learn that bare selectors only apply to
children of the scoping element, not the scoping element itself.
