The method that I tentatively call "Ranked Approval Voting" (RAV) is not 
simply Condorcet "completed" with Approval. (Condorcet completed with 
Approval would simply choose the Approval winner from the Smith set or 
from the entire set of candidates.) RAV uses Approval as an integral 
part of the rules rather than as an afterthought. As I said before, the 
approval scores naturally fill in the diagonal elements of the pairwise 
matrix. To my way of thinking, RAV is how Condorcet should work (or is 
at least one good way it could work).

If the EM community adopts this approach, you will be no further ahead 
in 30 years than you are today. I guarantee it.

Your last sentence leaves some hope.
