I appreciate after so many years to see the term "le belle Etage" reappear. I think I too belong to the group of people that have heard this sentence before and how an Architect in civil service thought to run ATC.!!
From what I remember from my years in "thin air control", routing and structure in south western German airspace was always a problem. May be a hint on "excessive" fuel consumption on lower FL may delay these unwanted early descends. Coordination on the ground should be not your concern, thats now a days only pushing some knobs, and workload is a too often misused phrase.
