Great point. I agree and have often thought about this. Kudos to Air China.
The only time that your model wouldn't work perfectly are the 1-1-1 and 2-1-2 configurations -- F should be a middle, but is actually on the aisle in these cases. (Maybe you could call the middle seat D (or H) in that case.)
But that's OK, these are not very common configurations, and, as you point out, would be in a premium cabin anyway.
