I beg to differ.

I said "if the exchange-point operator is the one carrying the
traffic," at the point where the subsequent comment depended on that
assumption. The preceding comments, particularly the ones regarding
administrative boundaries and who benefits, do not assume that the
exchange point operator carries the traffic:

- the message regarding the fact that more administrative boundaries
  make like more difficult at layer 2 is generic; (stated explicitly
  for you now) a system with three parties and two administrative
  boundaries (two EP switch fabrics and a carrier between them) has a
  *lot* of operational complexity and (I would argue) too many hands
  on the knobs - when what you are doing is collecting switch
  *fabrics* together.

- the operator of the L3 network that carries inter-EP fabric does not
  have to be either of the connected EP operators, which is why I
  called them by the name "operator of the L3 network" and not "EP
  operator."

That is, as you say, not a new solution.

PAIX has a segment of its existing customer base that use Ethernet
extend-o-technology to carry L2 frames between them and the port they
have leased on the PAIX switch with an ocean between them. With
respect to the exchange point layer 2 fabric, this is no different
than connecting a customer switch to the switch fabric (operationally,
we see no difference). Certainly some impressions from the folks at
the far end of those links would be of interest.
