Yes. RFC4007 and current practice already mean that interfaces and scopes
use the same namespace, and this would be a seamless extension.

Note that it's a completely unstructured namespace that's local to
the host. It maps straight into draft-carpenter-6man-uri-zoneid
in a very natural way, too.

(We are still far from having a proper handle on naming and addressing
scopes; but that is a very different question that I've been poking at
uselessly for a while:
