Which leads to the conclusion that the headers/id constructs should be kept
in the spec as a complement to the scope method, as it has *some* uses that
cannot be done with scope.

(as in: it's not just a problem of a specific UA or accessibility tool that
does not implement scope properly, it's also a broader problem that should
be kept in mind)
