PS - I disagree that the layer that's missing is the "AS" layer.
If that's what you really want, then you get that using a recursive

The result is precisely what happens if you add a true networking layer
below IP but above ethernet. And it includes the baggage that it should
- of cross-domain resolution for encapsulation.
